'Love, murder, betrayal, multiple universes and dinosaurs – amazing! One of the twistiest time-tales I've ever read' Diana Gabaldon

PANGEA, 201,320,641 BC: Quantum physicist Sam Anderson is trapped, 201 million years in the past. Sam has helped create a machine able to unpick the threads of time, casting objects eternally into the past. It's useful only as a permanent means of disposal – and in a world where criminals need to be punished, that's exactly how it will be used. But Sam's invention will become his undoing, the judicial penalty for a crime that he confessed to, but didn't commit. It's a death sentence.

Now he's on a raw and hostile planet, stalked by dinosaurs, in the midst of a mass extinction event, and unlikely to survive the night. But he can't give up, because he has to save his family, who are 201 million years in the future...

UNITED STATES, AD 2027: Adeline is an orphan – her mother died three years ago when she was sixteen, and her father is lost 201 million years ago, in the late Triassic. Adeline knows he sacrificed his life to save hers, but her determination to find the truth reveals more questions. What has unnerved her father's ex-colleagues? What are they secretly digging for in the desert?

Adeline will do whatever it takes to get to the truth, because somewhere, 201 million years in the past, her father is still alive...

Reviews for Lost in Time

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 * The Times * The book picks up like a great roller coaster. With a nod to John Varley's Millennium, the thrills in this mystery are not so much about who the killer is but how to save lives while maintaining their timeline * Booklist * Are we talking plot twists? More like spirals. Gripping, clever, mind-bending stuff * Daily Mail * A gorgeously dense and satisfying yarn... A hugely recommended high-concept page-turner * Starburst Magazine * [A] twisty-turny time travel caper, with a plot that could happily make a Bill & Ted sequel * SFX * Equal parts frenetic survival thriller and intelligent sci-fi study, Riddle's beautifully linear storytelling is a welcome change from more traditional time travel tales * SciFi Now * If time travel/science fiction/fantasy is your thing, you'll love this... It's all good fun and thrilling ride. Fasten your seatbelts * The Anglo-Celt * If you enjoy science fiction and time travel with your novels you will want to read Lost In Time by A.G. Riddle. The story features an interesting concept, believable characters and lots of suspense and adventure... A fascinating plot and lots of suspense make [it] an excellent read * Hero Mag * It's hard to beat a time-travel murder mystery with dinosaurs * Hero Mag * If you're looking for [a] page-turner with lots of silly action, cliff-hangers, and plot twists it's hard to beat a time-travel murder mystery with dinosaurs * Toronto Star *
