From the Kickstarter description:
Small towns are cauldrons full of family secrets. In Salem, those cauldrons bubble over. Inspired by paranormal cozies like Practical Magic and the Witches of Eastwick, White Picket Witches give the players magic and charms to deal with small town pressures... and sometimes, the forces of evil. It's about accepting the past, fitting in, or breaking out. It emphasizes friendships, brother/sisterhood, community, and a touch of romance.
