Rising Storm — Kat Gracey

Tempest Knox lives in Luna Bay, a small Island with a history of supernatural occurrences. Most of them caused by her family. She comes from a long line of witches.
When her grandmother disappears, it's up to Tempest to clear out her house. She discovers her grandmother's spell book hidden in a trunk. Tempest has never believed the witch rumors and while drunk, she reads a love spell.
The next morning she finds a naked man on the doorstep. Add to that a coven working out of the local tea shop and her grandmother's strange cat, and Tempest finds herself in over her head.
