DS7 just finished the Unicorn Chronicles series of books. I think the main character is a girl, but the author is male (Bruce Colville).
I haven't actually read the books but here's one review on Amazon:
"When I bought this book in third grade, I expected a girly story about Unicorns. I only bought it as all my friends did, too. When I got it, I read a page, got distracted, and left it to collect dust for ages. When I was in seventh grade, I finally had the sense to give the book a shot. I am sooooo glad I did. It is NOT a girly book about unicorns- it is a well written fantasy with deep characters and an intriguing plot. The story moves at a perfect pace, and it is a book I adore. I believe the title is very misleading. It is a great story, and it is right up there with Ella Enchanted, The Immortals Quartet, Harry Potter, The Forgotten Beasts of Eld, and The Changling Sea. Those are books you'd probably also enjoy if you enjoyed this."
