Frankie B: The Blood Hex - Marina Witches Mysteries, #2

Hexed blood. Murderous ghosts. Buried family secrets unearthed... Frankie thought vanquishing a spectral captain would cut her a break. She thought wrong. Now she's juggling a potentially fatal blood curse, hunting her mother's killer, and dealing with a father who's pulled a Lazarus act. Oh, and Grandma? The ex-pirate's stirred up a hurricane of trouble, because of course she has. Meanwhile, Frankie's new magical mojo is as reliable as a drunk fortune teller-sometimes explosive, often MIA.
But with fists of fury and a smart-mouthed familiar at her side, she's ready to smash through any obstacle. Training with Zane, the supernaturally hot warlock-merman hybrid, doesn't help her focus. Especially when their combined power threatens to rewrite reality itself. Will Frankie crack the hex, unmask a murderer, and untangle her family tree? Or will she flame out in a blaze of chaotic magic? One thing's certain: Normal is off the table, and Frankie's just fine with that.
