Smoke and Mirrors by K. D. Halbrook

She's part of the trapeze artists in this circus and she loves it.  She doesn't love going to school though.  There's a bully there that picks on her.

Paula Wiseman Books and Edelweiss let me read this book for review (thank you).  It has been published and you can grab a copy now.

They have a gray smoke that hovers around and causes trouble.  It's from a magician who has lost the one he loves.  She transformed into a whale and he can't transform, too. So he blames the circus and causes them trouble.

When the girl get disillusioned by school and the students, she makes a wish everybody would go away, including her mother.  The smoke rises up and both her parents turn into birds and fly in the smoke.  She didn't mean it.  Now how was she going to get them back?  She'll have to go to the edge of the world... 

She and her little brother fight monsters on the way and she finds out things about herself that will make her stronger.  

This is good action story that will keep you reading.  I wish there was more to this series.
