A magical adventure awaits young readers in, "Boo Who?," when a precocious girl named Gracie, her dog, Sniggles, and their friends; Bob, a crotchety crow; Lucy, an eccentric cat; and an anxiety-filled squirrel named Ziggy, befriend a fearful little ghost, Boo Montague, at the Hocus Pocus Pumpkin Patch. Boo was shunned by the other ghosts because he's cheerful, not spiteful and frightful. Gracie invites Boo to join them for Halloween. All is well until Sully the snail, who delivers the mail, arrives with a note from Annie Mc Fannie that reads, "Halloween has been canceled!" The gang embarks on an adventure to save Halloween, with help from retired wizard, Mr. Finkelstein. Tag along down Scaredy Pants Path, into Fairies Forest, and onward to Trick-or-Treat Trail searching for Creepy Street, while navigating all kinds of shenanigans and meeting whimsical characters along the way. Will the gang save Halloween, and Boo too?
