As two sisters watch their friends' families grow, they wish on a star for a sibling of their own...and a younger brother and a baby cousin arrive! The new family members aren't exactly what the sisters expected, but with time and patience, the group soon becomes fabulously four--and lets their imaginations soar! Together they can be anything, and no matter what, they will always remember that love comes first.

Inspired by Jenna and Barbara's own families, this companion title to the #1 New York Times bestseller Sisters First is a tender story about the way our hearts can always make room for more.
