About this book
When a secret Navy unit called SYLO descends on Pemberwick Island, Maine, they quarantine everyone, claiming a deadly virus is on the loose. Fourteen-year-old Tucker Pierce isn’t sure what to believe as strange events, mysterious technology, and mounting dangers close in. With the mainland cut off and trust in short supply, Tucker and his friends must uncover the truth before it’s too late. Fast-paced action, high-stakes mystery, and cliffhanger twists make this a favorite for middle school and early high school readers.
Setting: Present-day Pemberwick Island, off the coast of Maine, under military quarantine
