Last weekend, I had the pleasure of spending my Sunday doing just about nothing aside from reading. My book of choice? SHIVER by Allie Reynolds, a compulsively readable, superbly entertaining locked-room mystery perfect for fans of Ruth Ware and Lucy Foley. SHIVER is pure “popcorn reading” material: lighter on violence but heavy on entertainment value, this engaging, relentlessly suspenseful mystery begs to be devoured in one or two sittings. In SHIVER, readers travel to the French Alps, where a group of friends are arriving for a reunion. Ten years ago, the group met while training for a snowboarding competition. That fateful winter, things took a tragic turn, and one of their own went missing. Fast forward ten years, and each member of the group has tried to move on… but this reunion is poised to bring old tensions, rivalries, and secrets back into the light. As the group settles into the resort where their reunion weekend is set to take place, they discover that things aren’t quite right. The resort is abandoned, with not a soul in sight. Then their phones go missing. And when they discover that the person they each believed invited them on this trip didn’t actually plan this getaway, things take a dark and deadly turn. Who called this group together? And who is behind the increasingly sinister events of the trip? Moving between present-day locked room mystery and flashback chapters that illuminate the dynamics and relationships between our central cast of characters, SHIVER is deliciously readable and delightfully chilling mystery fun. This book thoroughly exceeded my expectations and left me wishing it were even longer, just so I could spend more time with its engaging, endearing characters. SHIVER had me, the least-athletic person I know, ready to throw it all away and move to the mountains to take up snowboarding. If that’s not saying something, I don’t know what is. Readers who love the modern-day locked room mysteries of Ruth Ware and Lucy Foley won’t want to miss Allie Reynolds’ chilling debut.
