What Dies Beneath

Hali Waverly is in a good place in her life. She's feeling better after surgery. Her boyfriend Gray Hunter is moving his office closer to her tiki bar so they can work on their paranormal cases together. Everything is coming up rum-flavored.
Unfortunately for Hali, things are about to blow up again.
A jeweler's conference should be easy-they have at least one a month after all-but when a magical tsunami hits at the same time the vault is emptied, trouble becomes the name of the game.
There are a number of suspects-a shiver of shark shifters walking naked out of the water the night before doesn't help matters-but it seems the culprit might have ties to Hali's grandmother's coven.
Once upon a time, Hali's familiar Wayne worked for a witch...and then a warlock. Things didn't go well with either of them. When it seems one of those individuals is involved-and posing a threat to the entire beach-things explode.
Hali has never been fond of Wayne but she needs him for this particular mission. More importantly, he needs her. That means things are about to get ugly.
Magic is about to take over St. Pete Beach. Who will be left standing...or swimming?
