Mermaid to the Rescue

The last thing Brooke the mermaid needs right now is her mother showing up in Purgatory Falls to "help" her get organized to leave town. For one thing, she has a street fair to help with in a few days, and she's also just tripped over a headless man in an alley. She has murders to solve!
But she did make her family a promise that she would leave the paranormal town and return to the human world, so while she figures out if a series of murders might be the work of one serial killer, she weighs her options carefully. Adding to her confusion, all her friends want her to stay—except the one who matters most. Aiden, a dragon shifter she's become close to, seems strangely distant and might be planning a new life of his own.
Will dealing with a serial killer in Purgatory Falls be the biggest challenge of Brooke's life? Or will it be figuring out where she really wants to call home?
