«One of the twistiest time-tales I've ever read! An amazing story of love, murder, betrayal, multiple universes, dinosaurs – and just what 'causality' really means»

Diana Gabaldon

«Crichtonesque thrillers don't come much better than this intricate outing 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 Starred Review

«We're talking high-concept thriller here... there are many japes and high jinks ahead»
