Something Wicked (Phoebe Winchester Mystery, #1)

Recipe for a potion to demolish life as you know it:

Step one: pack up your life and move to your aunt’s old house in a small, sleepy town.
Step two: discover that she was a witch.
Step three: discover that you’re also a witch.
Step four: Add a sprinkle of butterflies for your childhood friend (who’s suddenly incredibly hot), a dash of prying neighbours who want you to leave their town and never come back, and – the key ingredient – a murder on the steps of your aunt’s old tea shop (which, as it happens, is also a magic apothecary).

Voila. Your spell is complete.
