Is Karen M McManus writing another book?

Simon's secret is that he was depressed, suicidal, and actually masterminded his own death. Simon wanted the notoriety of a school shooter but also wanted others to appreciate his genius. By framing the teens for his murder, he planned to ruin their lives while also taking his own.

A ton of copycat gossip apps have popped up since Simon died, but in the year since the Bayview four were cleared of his shocking death, no one's been able to fill the gossip void quite like he could. The problem is no one has the facts. Until now.

From the novel's very first page, Karen M. McManus establishes that the world of Bayview High is ruled by a volatile network of gossip, secrets, and lies. The novel's title is deceiving—it's not just one of the protagonists, but all four, who are lying to each other and often to themselves.

A stand-alone novel in the vein of McManus' breakout 2017 thriller, Two Can Keep a Secret is a murder mystery set in Echo Ridge, a small New England town that's hiding secrets. One of Us Is Lying was one of EW's best YA books of 2017, and is currently in development as a TV series at E!
