There is nothing Hazel loves more than autumn, the spookiest season. The only problem is, nobody else in her town seems to care. Everything changes when Hazel receives a visit from Ronnie Pumpkinseed, a supernatural pumpkin-headed ambassador for all things spooky. Ronnie teaches Hazel a special word for what she feels inside—Halloween!—and helps Hazel find the courage to be herself and follow her heart, even when it's scary.
