The high-school dramas of a girl growing apart from her social group, and trying to find a way to make new, better friends without completely ditching her old friends. It's a story of dealing with changing friendships, with a side helping of mental-health issues (the main character has purely-obsessional OCD, which she keeps hidden from the friends she's known forever) and discovering oneself through poetry. 
 On the one hand, it's nothing ground-breaking, but on the other, it's a well-handled, well-written, emotional take on the familiar material. Might need some hand-selling to high-school teens (the cover is maybe a little bland?) but it's a good one to have in the collection.
