The Glaser Family Book of Shadows is the spell book of the Glaser line of Witches, one of the six families that settled in Chance Harbor after fleeing Salem. Its current location remains unknown; it was probably hidden after the events of the Boatyard Fire.
A list of spells has yet to be determined but it is very likely that the book possesses many potions with herbs as ingredients, considering the fact that Sophie Ann Glaser was particularly gifted with the use of herbs.
