"Maggie Shayne's books have a permanent spot on my keeper shelf." -#1 NY Times Bestselling Author KAREN ROBARDS Hey, I'm Rachel de Luca, a self-help guru with a potty mouth and a penchant for crime-solving. My partner, soon to be husband if I can get over my paralyzing fear, is Mason Brown, a detective with the Binghamton PD. Ten years ago, professional mermaid Eva Quaid disappeared without a trace from The Sapphire Club. Now, my niece Misty is working at the same club, doing the same job. Coincidentally, (not) Misty's college roommate is in the thick of her self-produced true crime podcast about the same cold case. Misty has kept every bit of this from our way-too-close-for-privacy family. None of this would be a big deal, except that I've been having nightmares. It's my wedding day, and I look from my adoring groom to my twin nieces, face down in the shallows of the reservoir behind the altar. I dreamt, too, of a dying mermaid who's been trying to get my attention ever since. When my sister expresses worry about her twin daughters, Mason and I agree to do a little snooping-only to find Misty has been keeping some big secrets, and is not where she's supposed to be. Nobody knows where she is. I'm pretty sure that Misty's gone off the grid with her podcasting partner Zig to surveil their favorite suspects in the ten-year-old case of the missing mermaid. I'm even more sure the mermaid is dead, and that her killer is determined to keep their oldest, deadliest secret, even if it means taking another young woman's life. I have to find my beloved niece before my visions come true-the way they always do.
