I read this two or three years ago, but I think it was published before that. This story is probably the only book the author writes for a younger audience. I don't read her (I think it's a she) other books, so I'm unfamiliar with who she is, this story was suggested to me by a friend.
What I remember:
- The main character is a girl
- She goes to an academy in place of her brother because he wishes to do something else (or a physical disability, I think)
- Has to dress up as a boy because it is a school for only boys
- She meets this guy (North, I think he's called?) in the academy
- North protects her from a lot of the bullies
- She visits North's home planet
- At his home planet, they get mad at each other, I don't remember why
- They go back to the academy, North eventually finds out she's a girl
- A bunch of misunderstandings follow
- Happy ending like all romance books
Is there a book that matches this description?
