Once Upon Toad by Heather Vogel Frederick

Once Upon a Toad is about a girl named Cat Starr who lives with her astronaut mother in Houston, Texas, but when her mother is sent on a mission Cat is forced to stay with her father in Oregon.
She isn't that excited about the news only because she going to have to share a room with her real-life evil stepsister, Olivia. Just a couple days later when Cat can't take any more of Olvia  her great aunt appears out of no where. Something is going on.

What a magnificent story this is! I really like this story mostly because it is full of humor, mishief, and adventure. Great book for girls who like adventure and a modern fairytale.
I reccomend this book for ages 9-13.
