A familiar tail - Delia James

Unlucky-in-love artist Annabelle Britton decides that a visit to the seaside town of Portsmouth, New Hampshire, is the perfect way to get over her problems. But when she stumbles upon a smoky grey cat named Alastair, and follows him into a charming cottage, Annabelle finds herself in a whole spell book full of trouble. Suddenly saddled with a witch's wand and a furry familiar, Annabelle soon meets a friendly group of women who use their spells, charms and potions to keep the people of Portsmouth safe. But they can't prevent every wicked deed in town.
