She doesn’t want to have to pick one or the other. Families are made of love in this heartwarming story that shows there are lots of ways to be part of one.

* Booklist Starred Review *

A must-have...this is a delightful celebration of what makes a family…. Holzwarth beautifully renders the characters in a variety of hues, making the diversity showcased throughout one of the book’s defining features and adding to the emotional punch of the story. All of the families look different, but the love they share makes them the same. Absolutely recommended for all children’s collections and sure to be a storytime winner.”
