Trying to remember the name of a YA book

[[deleted user]]

This is really random, but I've been trying to remember the name of a YA book I read years ago. It was about a young girl named Tina who joins the circus to become an acrobat (I remember they called her a "flyer"). I can remember HER name, but not the name of the book. I'd love to get a copy of it, if it's even still in print, but I am at a complete loss to remember the title. Thought I'd see if anyone else happens to know.
