Quantum Radio

"Original, entertaining, deftly crafted, and inherently fascinating read from first page to last" -Midwest Book Review

"An author from the much-missed Michael Crichton school of speculative fiction . . . an enjoyable read for someone missing the likes of Jurassic Park" -SF Book

"Quantum Radio is Invasion Quartet done straight, and Operation Crossbow on steroids." -ParSec Magazine

"Fans of conspiracy thrillers will enjoy this . . . fast-paced, speculative tale about physics, secret messages and powerful organisations" -Canberra Daily

"PRAISE FOR A.G. RIDDLE:

"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, on Lost in Time.

"Are we talking plot twists? More like spirals. Gripping, clever, mind-bending stuff" Daily Mail.

"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, on Lost in Time.

"A gorgeously dense and satisfying yarn, a time travel puzzle box whose pieces eventually fit together in a climax that's as exciting as it's determinedly mind-bending. You'll quickly find yourself lost in Lost in Time; a hugely recommended high-concept page-turner" Starburst.

"We're talking high-concept thriller here... There are many japes and high jinks ahead"" -The Times, on Lost in Time
