F6 Mystery Thrillers

The F6 novels are mystery/thrillers set in the not-too-distant future. F6 was adopted by an international multi-governmental agency that doesn't officially exist. Throughout her childhood she was simply identified as F6, the sixth female baby adopted into the program. Now she changes identities as often as other women change their shoes, moving through the world completing top-secret missions and keeping her distance. She's just trying to do her job. Somewhere out there is one man who wants to stop her.




Adopted by an international multi-governmental agency that doesn't officially exist, her only genuine identity is "F6" - the sixth female baby adopted into the program. Now she changes identities as often as other women change their shoes, moving through the world completing top-secret missions and keeping her distance.

A chance meeting with a handsome stranger tempts her to lower her guard. A second encounter turns up the heat until he finds himself in the middle of a murder investigation being conducted by one of F6's former lovers. Now F6 finds herself using her skills, training and multiple identities to help a friend in trouble. Something she has never done before; something she's prepared to do just this once.

Sailing around the Caribbean on a luxury yacht as the guest of one of the world's richest men sounds like a dream vacation, but for F6 it is just another assignment. As far as her host is concerned, she is "Suzy Barr", spoiled, rich and lazy. In fact, she is deep undercover, keeping a close eye on his business deals and his personal life.

In spite of her years of training, a murder still takes her by surprise, especially when it looks like she might be the prime suspect. In order to stay undercover, she has to destroy her pocket computer before the police can get their hands on it. That leaves her cut off from her agency and forced to use all of her wits and her training to stay in character, solve the murder and get off the boat.

A handsome police detective proves a useful ally, but she can't trust him with all of her secrets. There is one person that might be able to help; she helped him out when he was tied up in a murder investigation, after all. Calling Alex Knight could cause more harm than good, however, especially when someone else winds up dead, and this time Alex might just be the most likely suspect.

On her own for the first time in her life, F6 needs to find a job. A position as an instructor at a school training espionage agents seems suitable. It isn't long before she's starting to regret taking the job, however.

The suspicious death of the most hated man at the school does nothing to reassure her. While the school's owner insists the man died of natural causes, F6 isn't convinced. A second death could have simply been an unfortunate accident, but the more she investigates, the more convinced she becomes that both men were murdered.

F6 is determined to find out what really happened at the warehouse the night her best friend, F7, died. In order to do that, she needs to track down the men who were working with F7 that night.

What she quickly discovers is that she isn't the only one looking for the men. She's shocked to learn that every single one of them is missing.

She'll need to use every bit of her training if she's going to be able to hunt them down before someone silences them forever.

F6 was part of an elite group of men and women who'd been adopted when abandoned while still developing in their ex-utero pods. That was the story she'd been told, anyway, and sheÕd never doubted it.

Now, circumstances are forcing her to question everything she believes is true. A return to her birthplace, Fallon, Nevada, seems the only way to find answers.

In Fallon, though, the men who were involved in creating the technology that allowed for her birth are being murdered, one after another.

F6 is going to have to do everything she can to protect the few who are left, at least until she can get the answers she wants.
