The Squad is the government’s secret weapon—elite spies hidden in plain sight. And they need Toby. There’s a classified information leak in Bayport, and Toby has the skills to retrieve critical intel from the only person who has it—the most popular boy at school.

But evil lurks in Bayport, and Toby’s recent glow-up has put a spotlight on her . . . which might just get her killed.
