Fangirl by Rainbow Rowell

Summary: "Cath struggles to survive on her own in her first year of college while avoiding a surly roommate, bonding with a handsome classmate who only wants to talk about words, and worrying about her fragile father."

Cath also struggles with separating from her twin sister while at college and dealing with her mother who abandoned them. To cope with her personal problems, Cath relies on writing fanfaction for her favorite book series, Simon Snow, (which is very similar to Harry Potter). Fangirl is unique in that it includes snippets from both the fictional Simon Snow series as well as snippets of Cath's fanfiction at the beginning of each chapter. 

I enjoyed the book overall, but the ending doesn't provide much satisfaction or closure.
