Eve Hallows and the Book of Shrieks by Robert Gray
Middle school fiction that I think even adults will enjoy. This is a funny and entertaining book and I will keep it on my e-reader so that when my kids are a bit older I will be able to read it to them!
Eve is a great character who really is developed well and is easy to like! There are tons of laughs when the family must learn to live in the world of humans and you just will not want to put this book down. So if your kids are board and Spring Break seems like it will last forever, introduce your family to Eve.
