"A love letter to Amy Dunne of Gone Girl." —Olivia Muenter, USA Today bestselling author of Such a Bad Influence and Little One

"Sharp, hilarious, and painfully relatable." —Monika Kim, author of The Eyes Are the Best Part

An electric binge-of-a-debut about a millennial antihero who seeks revenge on her ex-situationship with a hex, only for him to actually, literally die.

Lillian and Henry have been enjoying each other’s company, particularly in bed. Even though Lillian’s best (and only) friend calls it a “situationship,” Lillian knows better. And she has a plan to lock Henry down. She’ll be the best, most accommodating version of herself until he falls in love with her. But when Henry blindsides Lillian with a breakup instead of a love declaration, Lillian is left with no choice but to exact revenge with a hex.

Lillian expects Henry to grovel and come crawling back to her. What she doesn’t anticipate is becoming a prime suspect in his murder case when he’s found dead.

Desperate to control the narrative, clear her name, and assume her rightful place as Henry’s mourning girlfriend, Lillian’s pursuit of the truth will throw her into a dangerous tailspin, which may just upend her life for good.

A deliciously addictive novel that explores our darkest, most human impulses, A Good Person heralds Kirsten King as a striking new voice in fiction.
