What if your enemy needs a friend?
Lark's life really stinks. She's the new kid in town. Her mom is the new principal at school. Worse, Lark's dad is seriously sick. Everyone and everything seems out to get her-especially Jeff, the class troublemaker. No one sees how lost she feels. The only person who seems to understand her is Mr. Timothy, the kindly janitor with a knowing smile and a secret or two of his own. But one stormy afternoon changes everything. Lark and Jeff find themselves teaming up to solve a century-old crime, uncover hidden treasure, and face off against a terrifying demon cockroach. Along the way, they learn that not all bullies are what they seem, and sometimes the only way to heal the present is to confront the past.
