Twelve-year-old Molly and her ten-year-old brother, Michael, have never liked their seven-year-old stepsister, Heather. Ever since their parents got married, she's made Molly and Michael's life miserable. Now their parents have moved them all to the country to live in a house that used to be a church, with a cemetery in the backyard. If that's not bad enough, Heather starts talking to a ghost named Helen and warning Molly and Michael that Helen is coming for them. Molly feels certain Heather is in some kind of danger, but every time she tries to help, Heather twists things around to get her into trouble. It seems as if things can't get any worse. But they do—when Helen comes.

“Much like Donna Tartt’s The Secret History, M. L. Rio’s sparkling debut is a richly layered story of love, friendship, and obsession...will keep you riveted through its final, electrifying moments.” —Cynthia D’Aprix Sweeney, New York Times bestselling author of The Nest "Nerdily (and winningly) in love with Shakespeare...Readable, smart.” —New York Times Book Review On the day Oliver Marks is released from jail, the man who put him there is waiting at the door. Detective Colborne wants to know the truth, and after ten years, Oliver is finally ready to tell it. A decade ago: Oliver is one of seven young Shakespearean actors at Dellecher Classical Conservatory, a place of keen ambition and fierce competition. In this secluded world of firelight and leather-bound books, Oliver and his friends play the same roles onstage and off: hero, villain, tyrant, temptress, ingénue, extras. But in their fourth and final year, good-natured rivalries turn ugly, and on opening night real violence invades the students’ world of make-believe. In the morning, the fourth-years find themselves facing their very own tragedy, and their greatest acting challenge yet: convincing the police, each other, and themselves that they are innocent. If We Were Villains was named one of Bustle's Best Thriller Novels of the Year, and Mystery Scene says, "A well-written and gripping ode to the stage...A fascinating, unorthodox take on rivalry, friendship, and truth."
