Charlotte Kingsley wants a quiet school year, but that becomes impossible the moment Tom Hale crashes back into her life. They argue in hallways, fight in chemistry class, push each other into fountains, and somehow keep ending up in each other's arms at the worst possible moments. Every time Charlotte tries to avoid him, Tom shows up - catching her when she falls, teasing her until she snaps, and getting under her skin in ways she refuses to admit. As accidents, misunderstandings, and explosive chemistry pull them closer, Charlotte has to face the truth: the boy she claims to hate might be the only one she can't stay away from.
