"Clever historical twists are used to imagine how an Axis victory might have brought World War II to a very different conclusion. . . . A tense novel in which scientists race against time to help humanity determine its own destiny." --Foreword Reviews

"Love, murder, betrayal, multiple universes and dinosaurs - amazing! One of the twistiest time-tales I've ever read." --Diana Gabaldon on Lost in Time

"Crichtonesque thrillers don't come much better than this intricate outing from Riddle (The Extinction Trials), which combines a fantastic premise--a time-travel device known as Absolom is used to imprison dangerous criminals in the prehistoric past--with a closed-circle whodunit. . . . Riddle keeps the twists coming, including a mind-bending jaw-dropper that sets up the book's second half. By creating sympathetic and complex characters, the author makes suspending disbelief easy. Readers won't be able to turn the pages fast enough." --Publishers Weekly on Lost in Time
