One Killer Problem
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.
