But hear me out it would be good for boys and girls around Kindergarten to grade 4. It is both a funny read and a tense read. You have to understand it a Prince stuck as a nasty frog and can only be save by..... Can't let any spoilers out of the bag.
I will say my mom enjoys simple books like these. She has a thing for retelling classic fairytales and twists in mythology.
All in all I give it a solid 4 stars.
