Plus-sized P.I. Savannah Reid has no problem mixing business with pleasure - especially if that means a free trip while on the job. But when a gruesome murder rocks the boat, Savannah may finally be in over her head.

Nothing satisfies Savannah's soul like nabbing bad guys - except maybe indulging in a juicy novel. So when famed mystery writer Natasha Van Cleef invites the Moonlight Magnolia Detective Agency on an Alaskan cruise in exchange for some personal protection, Savannah is instantly onboard with the idea. The voyage goes smoothly - at least, until Natasha and her husband flee the ship without explanation and get killed in a suspiciously explosive crash.

Awash in regret, Savannah and the MM crew won't return home to San Carmelita until they expose whoever caused the fatal "accident". But Savannah and her team have their work cut out for them when they discover that Natasha's life was far more dramatic than any of her best sellers. Not only were her marriage and literary career splattered with bad blood, but the author also had a crazed fan tracking her every move. With suspects and clues flooding in by the boatful, it's all hands on deck as Savannah rushes to seize the murderer before she lands herself in hot water next.
