The Forest of Stars by Heather Kassner

Her mother is dying.  If that's not sad enough, her father disappeared a long time ago.  Then, on her deathbed, her mother tells her the wind grabbed him and he flew away.  Louisa knows she floats above the ground, so she must be like her father.  When her mother passes, she decides to go find him.

Henry Holt and Company Books for young readers and Edelweiss allowed me to read this book for review (thank you).  It will be published August 4th.

As she heads out on her own, she finds a carnival.  She flies over the fence and goes in looking for her father.  A boy has seen her and he's trying to catch her.  He eventually does and she suddenly finds herself with friends she never had before.

One of the women there offers her a place to stay as long as she helps with seamstress duties.  Every thing seems to be going well.  She can fly but can't land.  The boy helps her with that.  Then everything starts going wrong.  Someone is stealing magic...

Who can it be?  Then one of the friends disappears and they go to look for her.  They find where the magic stealer stashes her victims.  As they try to free Merry, Louisa uses her scissors.  That alerts the stealer.

There's a battle that either side could win.  The ending is dramatic.  This was a good read.
