All of This Is True - Lygia Day Penaflor, Bloomsbury Publishing

When four Long Island teens plot to meet Fatima Ro, the elusive author of their favourite novel, they're stunned when she befriends them and invites them into her eccentric life. Suddenly their lives seem charmed, and as they grow closer to their idol, they find themselves revealing their darkest secrets to her. But a year later, Miri, Soleil, Jonah and Penny are shocked to discover that Fatima's newly released YA novel is based on those same secrets. The revelations are devastating, and they can't escape the spotlight. The friends' interview transcripts, emails and journal entries reveal how willing they were to sacrifice everything to win Fatima's approval - and how those sacrifices led to a tragedy from which one of them will never recover.
