The series finale featuring "a heroine you'll never forget and a story that whips by at bullet speed" by the New York Times–bestselling author (Tess Gerritsen).
When you have no time left, you realize what you're really living for . . .
For Dr. Angela Rossi the past holds only pain and the future promises only an early death as Fatal Insomnia consumes her.
But Angie will never stop fighting. Especially now that she's learned that her disease—and the disease she's discovered in dozens of young children—isn't a quirk of heredity but rather the creation of an unknown cabal. 
While Angie explores the betrayals and lies that led to the Fatal Insomnia epidemic, Devon Price, whose daughter is also infected, uses his street skills to hunt those responsible. He'll do anything to save his daughter. Lie, cheat, steal, kill . . . it doesn't matter. Not as long as Esme is saved.
In the end, their only hope might be a desperate deal with the devil: the cabal behind the man-made Fatal Insomnia epidemic. A deal paid with blood. A deal not everyone will survive.
Praise for the Fatal Insomnia series
"CJ Lyons scores a major triumph . . . a remarkable medical thriller equal to the very best of Robin Cook or Michael Crichton. This intelligent, well-crafted novel, based on a startlingly original premise, builds up tension to the breaking point and beyond, delivering plenty of surprises along the way. Totally absorbing and impossible to put down." —Douglas Preston, #1 New York Times–bestselling author
