Heartstopper by Alice Oseman

Volume 1, Graphic Novel.

Boy meets boy. Boys become friends. Boys fall in love. Charlie and Nick are at the same school, but they've never met ... until one day when they're made to sit together. They quickly become friends, and soon Charlie is falling hard for Nick, even though he doesn't think he has a chance.

But love works in surprising ways, and Nick is more interested in Charlie than either of them realised.

Excellent condition.
