A darkly funny and thoroughly queer mystery thriller with a touch of camp, for fans of Kara Thomas and Kit Frick by way of Only Murders in the Building.

When Gianna “Gigi” Ricci lands in detention again, she doesn’t expect the glorified study hall to be her alibi.

But when she and her friends receive a mysterious email directing them to her favorite teacher, Mr. Ford’s room, they find him lying in a pool of blood. But calling the math teacher’s death an accident doesn’t add up, and Gigi needs all the help she can get to find the truth. Luckily, she’s friends with her high school’s “mystery club,” and so with her best friend, Sean, and longtime crush, Mari, Gigi sets out to solve a murder.

But it turns out, murderers are extremely unwilling to be caught, and the deeper Gigi gets in this mystery, the more dangerous things become. Between fending off a murderer, continual flare-ups of her IBS, and her archnemesis turning flirtatious . . . making it out of junior year is going to be one killer problem.

With a wry, hilarious voice and a main character who is the walking definition of a disaster bi, this book is an ode to cozy mysteries, queer found families, and fighting for the people you love, no matter what.
