Picking up almost immediately after where SLEEPER CODE ended...

Tom Lovett is locked in a battle. A battle with himself. Or, more accurately, a battle with Tyler Garrett, the second, deadly personality that The Janus Project created to exist in Tom when he "sleeps." The winner gets to live. The loser ceases to exist.

When Tom has a narcoleptic attack, Tyler Garrett takes over. That's how it's supposed to work, anyway. But now that Tom knows about Tyler, the barrier between the two is braking down. Tom and Tyler's memories are beginning to blend, as are their personalities. Tom has flashes of memories of death and destruction, and Tyler experiences moments of doubt and guilt.

With Tom's psyche weakened by experiments, all it takes is a whisper from the woman who masqueraded as Tom's mom and Tyler Garrett is back. Literally hanging on for his life.

Tyler escapes the Pandora facility to fulfill a mission. He's stuck with Madison, who believes he's Tom, and whom he can't seem to manage to kill or discard. All the while, Tom is locked in a mental prison, fighting for his life, and Madison's, and possibly the continued existence of the world, to escape.

Personal demons are truly life-like in this story of danger and strength. Who do you trust when you can't even be sure you can trust yourself?

As action-packed and fast moving as the first book. Tom Sniegoski doesn't miss a step in the continuation of the story. It goes deeper and gets darker then could be imagined. So well-written that I even almost felt bad for the villain. But it all comes down to choices, in the end. Reading this book is a good one. ( )

See the review listed under the first book in this series, SLEEPER CODE. ( )

This book picks up where Sleeper Code left off. Tom is being studied at the Pandora facility to find out the extent of the Janus project, a project that has used his narcolepsy as a cover for his alter-ego and assassin, Tyler Garrett. Tom and Tyler are waging war over Tom's body to see who will become the dominant personality, while Brandon Kavanaugh is being hunted by the Pandora project. The narrative feels choppy at times flipping between the story lines. There is plenty of action and fight sequences within the story. I don't think this volume would stand alone very well and may be quite confusing for those who hadn't read the first installment. ( )
