Penumbra

Agent Sam Ryan has had enough. She wants out, and she wants out now. She's sick of putting up with Gabriel's crappy attitude, sick of seeing nothing but paperwork and the inside off her small office. But most of all, she is sick of feeling lonely. It's time to take control and get a life outside of work. But Stephan, the man in charge of the SIU, isn't about to let her go easily.

Offered the choice between guarding a clone and probable enemy of the country, or remaining stuck in her shoe box, Sam reluctantly accepts the former, even though she suspects Stephan is using her as bait to draw out the elusive and dangerous Sethanon.

Gabriel is relieved to discover he's finally shaken Sam as a partner, until he learns her new assignment is guarding Wetherton, the clone replacement of a government minister. Both he and Stephan know Wetherton could only have come from one place – Hopeworth. The military base has been involved in DNA experiments for decades and was more than likely the place where Sam was created. But there is a growing likelihood that the military base is also the home of Sethanon himself.

Determined to protect her, Gabriel is quickly drawn into the mission. All too soon he discovers the connection between he and Sam is far deeper than anyone could ever have imagined. As the assignment begins to unravel around Sam and her past begins to reveal itself in her dreams, she fights to stay alive because the military wants their creation back. And the only person standing between her and them might well be the enemy of all mankind.
