Fifteen years ago, Maia Gold attended a prestigious—and very exclusive—writers retreat hosted by billionaire Argos Alexander on the Greek island of Eris. It’s where she wrote her first book, the one that should have launched a brilliant career. But something dark happened on that island, a betrayal that has hung over Maia ever since.

Now, Maia finds a familiar envelope in the mail. It’s an invitation to return to Eris, and according to social media, she’s not the only one from that first retreat who’s been invited back. This could be the second chance Maia needs to jump-start her dreams. A chance for reconciliation… or revenge.

Almost all of the writers from fifteen years before have returned to Eris, bringing unresolved resentments with them. Soon, the guests learn that their illustrious host is absent, though he has left instructions for them to participate in a contest: whoever can write the most suspenseful mystery while on the island will win a fortune and literary acclaim. But this is no harmless game—when the guests gather in the morning to share their first chapters, they find Argos Alexander, dead.

Tensions simmer as the guests try to determine who’s capable of murder, not just on the page, but in real life. On an island full of mystery writers, anyone could be the killer—and anyone could be the next victim. Trapped together until the next boat arrives from the mainland, they must sort out old grievances and figure out how to trust one another... or die one by one.
