This charming story about three California sisters spending the summer on Cape Cod is perfect for fans of The Penderwicks—as a starred ALA Booklist review raved—and The Mother-Daughter Book Club.

Though Marigold, Zinnia, and Lily Silver couldn’t be more different, they’re all excited about summer vacation. Twelve-year-old Marigold is hoping to get her first kiss from her big crush, while Zinnia, eleven, will most likely spend her time in Marigold’s shadow. And five-year-old Lily, though angelic, has a knack for stirring up mischief wherever she goes.

But all of their plans come crashing down when the sisters’ parents send them to Cape Cod to visit their Aunt Sunny. Small-town life is not what these LA girls had in mind. They must adjust, however, to things like sharing a room and living without a TV. With the help of Aunt Sunny’s cheery disposition and her yummy brownies, though, the girls are quickly won over, and before Marigold, Zinnie, and Lily know it, they’re cracking lobster shells at clambakes, making new friends, and even organizing a local talent show.

Full of moments both humorous and reflective, The Forget-Me-Not Summer is a story about three girls facing their fears, adjusting to change, and learning how to band together as the strongest version of themselves: sisters. Be sure to catch the sequel, The Brightest Stars of Summer, for more fun on Cape Cod!
