After Willa's parents' divorce, Willa and her mom find themselves starting fresh in the country town of Plunkit. Catching a glimpse of a sparkle by the creek and in the old woods, Willa knows there's something unusual about her new surroundings. And her older-than-old neighbor, Hazel Wicket, has an amusing story about an imagined family of tiny people that inhabit a tree stump.

Willa knows there's no such thing as fairies, but when she spots more and more oddities, she can't stop wondering if there's some truth behind Hazel's curious tales of the fairies called Nutfolk. . . .
