Jenna Miller writes some great contemporary YA books about fat lesbians and is now definitely on my "look out for everything she publishes" list.

This was a pretty addictive read you fly through. The story flows really well.
I did appreciate the story and the characters but there were times where I found myself quite critical towards our MC, mostly in her way of not understanding her crush's potential difficulties (with coming out for instance) which I found too hurtful.
But it does also feel like a book where the characters feel pretty real, make mistakes, and own up to them. It's a good growth story.
