Here we find  cyber agent Seph Carano, the series’ main character, meeting with an informant who calls himself Dante who claims to have information for her about an impending cyber attack.

 

 

The Grey Dog was a block off Seventh Avenue and only a short walk from Seph’s office. It was the first breakfast place she had discovered when she began working at the Cyber Security Agency. She remembered lively crowds lining up outside the bustling storefront, drawn by the promise of a hot, comforting breakfast to start their day. Some folks had stood patiently in the queue, scrolling through their phones or chatting with friends, while others bounced on their feet with the aroma of bacon making their mouths water. Online ordering had changed the scene. Now customers ordered in advance using the Grey Dog’s app, so when they arrived, their meals were waiting for them. They grabbed the bags labeled with their names and were gone in a flash. There were no more lines, but the constant flow of cheerful patrons in and out of the shop had created a festive atmosphere. Seph had texted ahead, so her latte and egg and cheese croissant were bagged up when she reached the counter. She found a table at the rear of the room where she could watch for Dante. She split the crescent and neatly wrapped the larger piece to save for lunch.

 

Seph had finished the croissant, refilled her latte, and was debating ordering a fruit cup when Dante arrived. Again, he was dressed like a fashion icon, this time in tan slacks, a navy blazer, and a powder blue shirt. Why would a cyber-hacker even have such stylish apparel? At the counter he ordered chorizo hash, glimpsed Seph at the back of the room and smiled. She resisted commenting on his appearance when he came to the table and said brusquely, “I’m eager to hear what you have to tell me that couldn’t be said on the phone.”

 

Feigning wounded feelings, Dante responded, “You’re a bit testy this morning. Have I offended you? You know I’m a friend, don’t you?”

 

“All I know for certain is you once kept a town’s water supply from being contaminated by closing a valve on an oil pipeline.”

 

Dante’s smile broadened. “Ah, so you’ve been looking into my past. My involvement with the pipeline was the act of a young lad, but it proves I’m a good guy, doesn’t it?”

 

“I need more than a single instance to make a judgment.”

 

 “What else have you discovered about me?”

 

“Very little, except you’re discreet enough to avoid the limelight.”

 

“True, but if there’s something you’d like to know about me, just ask. I’ll share almost anything…almost anything.”

 

A server came to the table with Dante’s breakfast platter. Seph declined when the server asked if she wanted her latte refilled again. Hoping to catch Dante off guard, Seph waited until he’d taken a bite before asking, “What’s your real name?”

 

Her ruse failed. Dante finished chewing, then replied calmly, “I’m willing to share general information, but my name is too specific.”

 

Wanting to avoid wordplay, Seph snapped, “I agreed to meet because you claimed to have urgent information. What is it?”

 

“I’ll tell you after I’ve eaten because if I tell you now, you’ll leave. I came to the restaurant of your choice, expecting we could enjoy a meal together. Even though you’ve finished eating, grant me the pleasure of your company while I savor the Grey Dog breakfast special.”

 

Seph groused, “You’re insufferable.”

 

Dante said, “Most confidential informants expect to be paid for their information. All I’m asking for is pleasant company.”

 

“You fancy yourself a confidential informant? Where do you get your information? We have investigators who monitor the dark web constantly, and they haven’t seen any posts hinting at an attack on the Bridges and Tunnels Authority.”

 

“Your investigators monitor the chat rooms, but the most meaningful exchanges don’t take place in those public spaces. Serious issues are discussed in private channels accessible only by invitation.”

 

“And you participate in the private forums, I presume?”

 

“I do. I earned entry long ago, when I was a teenager.”

 

“We checked our database, and there’s no trace of anyone using the name Dante on the dark web more than seven years ago. Nothing from the time when you would have been a teenager.”

 

“I was a different person those many years ago. I became Dante when….” He searched for the right phrasing. “When I was re-born, and please don’t ask about my metamorphosis. It wasn’t a pleasant experience, not one I wish to dwell on.”

 

 “You expect me to trust you; yet you admit to frequenting invitation-only forums swarming with cyber criminals, you won’t tell me your real name, and you keep your past hidden. You don’t give me much of a basis for trust.”

 

“We have different values, Seph. For example, while I might find it acceptable, even laudable, for someone to hack into the network of a bank charging usury loan rates to poor working people, I’m sure you would call the intrusion a crime. However, I’m sure we’d both consider it intolerable for anyone to disrupt the city’s infrastructure for his own personal gain.”

 

Silence hung in the air for a long minute. Dante broke it, saying, “Since our last meeting, I learned Needle24 has been recruited not just to breach the Bridges and Tunnels Authority, but to stage a series of coordinated attacks. The plan isn’t fully developed yet, but it will include attacks on different parts of the city’s infrastructure. The messages I saw mentioned subways, traffic lights, ferryboats, and airports, although those are merely options under consideration. And the purpose of the attacks is to make the present city administration appear incompetent.”

 

Seph stared in disbelief. “Did I hear you correctly? You’re saying cyber attacks will be carried out to make the mayor and his administration look bad?” Her eyes narrowed. “Someone wants to influence the election. Who?”

 

“I don’t know. The person pulling the strings is keeping his identity hidden.”

 

“Are you sure about this?”

 

“I’m sure.”

 

“What’s the timeframe?”

 

“The exact date hasn’t been decided yet, but it will have to be soon—before election day.”

Getting to know Seph Carano:  a Tech‑Savvy Hero With Relatable Human Qualities

 

The main character in my new Cyber Case series is a woman named Persephone “Seph” Carano. She’s an Incident Responder for the Cyber Security Agency, the person who gets called when something strange, suspicious, or downright dangerous happens inside a computer network.

 

If you’re picturing James Bond with a laptop or James Bourne chasing cybercriminals through Manhattan, you’re in the right neighborhood, but Seph isn’t modeled on either of them. She’s not a spy, not a superhero, and not a lone wolf who solves everything with a punch or a pistol. She’s a highly trained professional who walks into digital chaos and brings order to it with the presence of an actual human being. And to write a character like that, I had to understand her far beyond her job description.

 

Before I ever wrote a chapter of Book 1, I wrote a separate piece about her childhood, her school years, her time at Carnegie Mellon, and the early experiences that shaped her. None of that appears directly in the novels, but I needed it. I needed to know what kind of person she is, what she wants, who she trusts, and why she chose a career where most people only call her when something has gone terribly wrong.

 

Once I understood her, she could show up on the page exactly the way I hoped she would. There’s a scene early in Book 2 where she’s called into her boss’ office. The room is thick with tension. He’s scowling, and others in the room are fidgeting nervously. He hands Seph a vague alert about a file that failed an audit test. Instead of panicking or trying to impress anyone, she simply says, “There’s no mention of a breach. Only that there was an error in a file’s byte count. I’ll call the tech center to find out what’s going on.” Calm, direct, and completely unflustered. That’s Seph, methodical and analytical.

 

Cyber incidents are never just about corrupted files or malware. They’re about people who suddenly feel exposed, vulnerable, or responsible for something they don’t understand. That’s why Seph’s first instinct is always empathy. When the chief technician at the Bridges and Tunnels Authority calls her to report an incident, she doesn’t interrogate him. She listens and adjusts her tone when she realizes he’s used to being talked down to by others at her agency.

 

Her approach makes their conversation feel less like an interrogation and more like a collaboration. She knows people tell her more when they’re not being intimidated. She learns enough from their discussion to analyze the breach and guide the technician through the steps needed to restore his network.

 

Her humanity really shines in her relationship with her sister, Serenity, who is a grad student at NYU. One of my favorite scenes is when Seph drops by Serenity’s dorm room. Serenity is buried in books, wearing ratty sweatpants and an oversized sweatshirt that smells like lavender and cheese doodles. She’s wrestling with a paper for a political science class and already predicting sleepless nights. Seph doesn’t tease her or lecture her. She just asks, “What’s the topic?” and listens patiently, giving Serenity the opportunity to vent about how complex rules in the US Congress make life tough for grad students.

 

Their roles flip when Seph needs support from her sister. Seph just came from her office. She’s wearing a business suit, hardly suitable for attending a hockey game with a date. Serenity immediately tosses her an NYU sweatshirt and points her toward a “reasonably respectable” pair of jeans. They banter about who looks younger and who dresses better. That’s the Seph who laughs, the one who leans on her sister, the one who isn’t always the calm professional with her head in the cyberworld.

 

Readers connect with Seph because she’s competent without being perfect. If she makes a mistake, she recalibrates and moves on. In the Bridges and Tunnels case, she initially assumed the byte‑count anomaly was a minor glitch. But when the technician calls back in a panic, she pivots instantly. No defensiveness. No excuses. Just action. She frets about not having anticipated the problem, then immediately grabs her analyst, heads to the site of the hacked network, and gets to work. She’s not infallible; she’s adaptable.

 

Seph didn’t choose cybersecurity because it was glamorous. She chose it because she saw how easily ordinary people can be hurt by things they don’t understand. So she gets so angry when she sees sloppy security practices like dating apps and personal email accounts on critical workstations. She gets furious when incompetence puts people at risk.

 

All of this makes Seph feel real. Brilliant, yes, but she’s also compassionate, frustrated, tired, determined, and occasionally exasperated. She’s someone you could imagine working with, or being friends with, or trusting in a crisis. She’s not a fantasy; she could be the woman living in the apartment next door.

 

That’s the balance I’m always chasing when I write her. And I think that’s why readers want to follow her from case to case. She’s not larger than life. She’s life-sized.
