Understated and heart-warming, this is a story of love and determination that shows how everyone can be a superhero in their own way.

When Adam meets Robyn he is drawn to her almost before he can take a breath.

He's determined to protect and defend her, to play Batman to her Robin, whatever the cost.

But when you're fourteen and the everyday problems of dealing with divorced parents and step-siblings are supplemented by the challenges of OCD, it's hard to imagine yourself falling in love.

This beautiful story will appeal to readers of John Green.
