Device Free Weekend by Sean Doolittle
My rating: 5 of 5 stars
An utterly absorbing, totally unique locked-room thriller in which seven college friends reunite for a weekend on a secluded island, with no technology allowed. But when the organizer of their weekend, tech billionaire Ryan Cloverhill, presents them with an ethics, trolley-type problem to solve, the weekend descends into one of survival. And not all of them will make it out alive. An action-packed thriller that I absolutely couldn’t put down. Breathtaking!
