The immeasurable depth of you

Fifteen-year-old Brynn can't stop thinking about death. Her intrusive thoughts and severe anxiety leave her feeling helpless -- and hopeless. So after her mom interprets one of Brynn's blog posts as a suicide note, she takes extreme measures, confiscating Brynn's phone, blocking her Internet access, and banishing her to stay with her father who lives "off the grid" on a houseboat in the Florida mangroves. Isolated from her online friends -- her only friends -- Brynn resigns herself to a summer of mind-numbing boredom and loneliness ... until Skylar appears. Skylar is everything Brynn isn't -- sultry, athletic, and confident. Yet Brynn feels at home around this fearless girl who pushes her to try new things and makes her belly flutter with nerves that have nothing to do with anxiety. When Brynn discovers that Skylar is trapped in the bayou and can't tell her why, she resolves to free her new crush from the dark waters, even if it means confronting all of her worst fears.
