Sixteen-year-old and not-so-openly gay Simon Spier prefers to save his drama for the school musical. But when an email falls into the wrong hands, his secret is at risk of being thrust into the spotlight. And worse still, so will the privacy of 'Blue', the pen name of the boy he's been emailing. With messy dynamics emerging in Simon's once tight-knit group of friends, and his email correspondence with Blue growing more flirtatious every day, Simon's life suddenly becomes just a little complicated. Now Simon has to find a way to step out of his comfort zone before he's pushed out - without alienating his friends, compromising himself, or fumbling a shot at happiness with the most confusing, adorable guy he's never met.
