The Fury by Alex Michaelides

There were seven of us in all, trapped on the island. One of us was a murderer . . .' On a small private Greek island, former movie star Lana Farrar - an old friend - invites a select group of us to stay. It'll be hot, sunny, perfect. A chance to relax and reconnect - and maybe for a few hidden truths to come out. Because nothing on this island is quite what it seems. Not Lana. Not her guests. Certainly not the murderer - furiously plotting their crime . . . But who am I? My name is Elliot Chase, and I'm going to tell you a story unlike any you've ever heard.
