Be careful what you believe in.
Rudy’s life is flipped upside-down when his family moves to a remote island in a last attempt to save his sick younger brother. With nothing to do but worry, Rudy sinks deeper and deeper into loneliness and lies awake at night listening to the screams of the ocean beneath his family’s rickety house.
Then he meets Diana, who makes him wonder what he even knows about love, and Teeth, who makes him question what he knows about anything. Rudy can’t remember the last time he felt so connected to someone, but being friends with Teeth is more than a little bit complicated. He soon learns that Teeth has terrible secrets. Violent secrets. Secrets that will force Rudy to choose between his own happiness and his brother’s life.
