Runner 13 is a must-read for anyone who loves high-stakes survival stories packed with personal redemption and dark secrets, all set in the intense, unforgiving world of ultrarunning. As someone who’s fascinated by ultrarunners, I couldn’t wait to dive into this one — and it did *not* disappoint. I raced through the pages (pun absolutely intended!), torn between not wanting it to end and needing to know what happens next. This book is an absolute rollercoaster — fast-paced, gripping, and impossible to put down. Trust me, it’s a thriller you’ll want to talk about, and I’ll definitely be recommending it to everyone!
