At Hogwarts, Bianca Sinclair has one problem—she can’t date unless her older sister does first. The problem is… her sister doesn’t date. Ever. She’s sharp-tongued, impossible to read, and completely uninterested in anyone who breathes too loudly. So when Lorenzo Berkshire decides he’s done waiting, he strikes a deal with the last person anyone expects to get involved: Mattheo Riddle. It’s supposed to be simple—pretend, convince, move on. But Mattheo doesn’t do simple. And you don’t do him. Until suddenly, you do.
