Together they can be anything, and no matter what, they will always remember that love comes first."

The book is inspired by Jenna and Barbara’s own families, the publisher says, and is a companion to their No. 1 New York Times bestseller Sisters First, "a tender story about the way our hearts can always make room for more."
