The Girl who Chased the Moon by Sarah Addison Allen

Emily Benedict has come to Mullaby, North Carolina, hoping to solve at least some of the riddles surrounding her mother's life. But the moment Emily enters the house where her mother grew up and meets the grandfather she never knew, she realizes that mysteries aren't solved in Mullaby, they're a way of life: Here are rooms where the wallpaper changes to suit your mood. Unexplained lights skip across the yard at midnight.

And a neighbor, Julia Winterson, bakes hope in the form of cakes, not only wishing to satisfy the town's sweet tooth but also dreaming of rekindling the love she fears might be lost forever. Can a hummingbird cake really bring back a lost love? Is there really a ghost dancing in Emily's backyard? The answers are never what you expect. But in this town of lovable misfits, the unexpected fits right in.
