Young wizards, witches, and muggles are invited to the West Tisbury library on Feb. 2 for a night of spells, magic, and Harry Potter. The fun kicks off at 4 pm with a Sorting Ceremony, where the Sorting Hat decides who will be in each house. Then create spells, potions, read from your favorite Harry Potter books, and snack on wizarding-world-inspired food. Costumes are welcome. Free. This event is co-sponsored by the library and the Martha’s Vineyard Public Charter School.
