Found: YA Fiction early 2000s "Chinese girl learns martial arts dressed as boy and chosen by dragon."

Hey! I am looking for a book about a young chinese girl that had a leg injury and was taken by a martial arts teacher to become a dragon warrior. She is made to act and dress like a guy. She is chosen by the dragon from the chinese zodiac out of season since it was the year of the rat. I read this 4 years back, it had a red cover with gold letters

Thanks for your time and help in advance!

That sounds like Eon by Allison Goodman, although it might be too recent.

>2 Mialro: It is!! Thank you very much!!!! I loved the book I read the book 4 years at school were it mysteriously appeared on top of a desk in a stock closet and I read it but couldn't for the life of me figure the title out again. Thank you so much.

Touchstone: Eon: Dragoneye Reborn by Alison Goodman

I came here to say the same - there is a sequel as well: Eona, though I haven't read that.
