Midnight Victories - L. K. Latham - Bog

Clara loves a good fight: beating the odds, defending what's right, and valuing those around her.
She fought to build the perfect life in Galveston, and she's loved every battle. When the Army arrives, led by a handsome colonel, she decides her life is complete. But something isn't right.
A tourist disappearing at the height of the season is nothing to worry her, but more than tourists are missing. Instead of walking in the moonlight and enjoying the soothing song of the Gulf waters, fear, like fingers of ice, wraps around her.
Something is changing. Even Gaston, her favorite dog, is acting strange. He's loving one moment, hiding in a corner the next, and growling at her the next. Actually, all the pets in her veterinary practice are acting strange, especially when her best friend shows up.
John, the lover she's been waiting for, is worried but tells her it's nothing.
Clara knows something is up. She paid attention when her grandmother told her stories of things not quite human and how they hide in shadows. If Clara's going to save her home, her island, and those she loves, she'll need all her fighting skills to find the truth.
The problem with knowing the truth, it can't be unknown.
