The irascible A. J. Fikry, owner of Island Books—the only bookstore on Alice Island—has already lost his wife. Now his most prized possession, a rare book, has been stolen from right under his nose in the most embarrassing of circumstances. The store itself, it seems, will be next to go.
One night upon closing, he discovers a toddler in his children's section with a note from her mother pinned to her Elmo doll: "I want Maya to grow up in a place with books and among people who care about such kinds of things. I love her very much, but I can no longer take care of her." A search for Maya's mother, A. J.'s rare book, and good childcare advice ensues, but it doesn't take long for the locals to notice the transformation of both bookstore and owner, something of particular interest to the lovely yet eccentric Knightley Press sales rep, Amelia Loman, who makes the arduous journey to Alice Island thrice each year to pitch her books to the cranky owner.
