The Stone Rainbow — Liane Shaw

Jack Pedersen is finding life complicated ever since he came out to his mom. Even though she's been doing her best to understand, it's obvious to Jack that his mom still wants to cry every time she says the word gay.  

Complications go into overdrive when a new student named Benjamin arrives at his high school, and Jack starts experiencing feelings he's never allowed himself before. When a near tragedy turns life upside down, Jack realizes that it's time to stop hiding and to stand up -- for Pride, for Benjamin, and for himself.
