For months, Cass has heard her best friend, Julia, whisper about a secret project. When Julia dies in a car accident, her drama friends decide to bring the project—a musical called Totally Sweet Ninja Death Squad—to fruition. But Cass isn’t a drama person. She can’t take a summer of painting sets, and she won’t spend long hours with Heather, the girl who made her miserable all through middle school and has somehow landed the leading role. So Cass takes off. In alternating chapters, she spends the first part of summer on a cross-country bike trip and the rest swallowing her pride, making props, and—of all things—falling for Heather.
