If there was a race to write a dark, immersive thriller that will transport you to a whole new world (of extreme marathon running) then Runner 13 by Amy McCulloch would be first across the line. A masterclass in atmospheric writing, it is told with resounding skill and authenticity, as deadly events at the extreme end of competitive running threaten the lives and families of troubled participants. This is gold medal storytelling and I raced through it. -- JANICE HALLETT
Runner 13 is an utterly brilliant immersive thriller set in a terrifyingly arduous adventure race think Agatha Christie meets Marathon de Sables meets the Barkley Marathons. It is smart, visceral, deliciously dark and twisty. -- LOUISE MINCHIN
Brilliantly atmospheric and with relentless pace, Runner 13 is one of the most propulsive adventure thrillers I’ve read. It will leave you gasping for breath. I loved it! -- Liv Matthews
Amy McCulloch does it again! Runner 13 is an absolute scorcher of a thriller that examines the lengths we are willing to push ourselves for what's right. Each chapter left me out of breath and desperate to learn what would happen next. Reading this book was a race to the very last page. All in all, Runner 13 proves that no one does an adventure thriller quite like Amy McCulloch. -- SARA OCHS, author of The Resort
A thriller set around the fascinating world of ultra-running where there's always the threat that even the race might kill you. Utterly breathtaking - absolutely loved it. Amy's best yet -- CATHERINE COOPER
In Runner 13, McCulloch's firsthand experience of ultra running shines through every page. I felt like I was there! A fast-paced adventure thriller that will get your pulse racing. Not to be missed -- LUCY CLARKE
Tense, exhilarating and deeply immersive, I raced through this epic ultramarathon thriller. So good on character, with a layered plot and vivid desert setting—I loved it as a runner, a reader, and a full-of-admiration writer -- LAURA STEVEN, #1 New York Times bestselling author of Our Infinite Fates
As soon as I finished it I ordered all Amy's other books. A breathless, complex thriller. I steamed through it -- JANE FALLON
