Fitting in is impossible for Peter Mulligan--the class "weirdo." Bullies won't accept his quirky sense of humor, his obsession with movies, or his autism spectrum disorder. At the end of the school year, an insensitive classmate picks on him during a state-wide exam. Peter has a tear-gushing meltdown in the middle of the test. After the incident, Peter's parents send him to live with his no-nonsense grandmother on isolated Johnson Island for the summer. But something seems off. Peter discovers that the creatures featured in his favorite flicks are nothing compared to real-life monsters. Now, the weirdo must become the hero. If he doesn't, Peter and his newfound friends will never save the island from sinister seed experiments gone very, very wrong!
