Cold as a Witch's Tequila Sunrise

The big day has arrived. Hali Waverly is finally getting the surgery she so desperately needs. Her boyfriend Gray Hunter is determined to be by her side for it. She thinks she's ready for it. Is she, though?
The surgery itself goes off without a hitch. Hali's recovery is another story. Ceding control of her beloved tiki bar to her brother and her boyfriend's brother only amps up her anxiety. Things get worse when a storm hits, and it's of the magical variety instead of the natural. When a body is found in the aftermath, things are bad.
Things get worse when the body is identified as belonging to a local pack member, and the last person seen with the woman is Gray's mother. Helene, of course, denies being up to anything nefarious. Unfortunately for her, Hali is in on her big secret, and it's time to share it.
Hali thought the hardest thing in the world would be the surgery. She was wrong. Now she has to tell the man she loves about his mother's betrayal and keep him from cutting his parents out of his life forever because of it.
It's not just the pack closing in, though. The dark merrow are also making their move. Hali's small sliver of beach is about to become very crowded.
Even though this is the exact worst time for a war, Hali finds herself embroiled in one. One side will fall forever. Hali wants to be on the winning team because if she's not, they'll all die.
The big battle is here.
