This tale of the irresistible and unforgettable Mrs. Plansky, "a terrific character" (Stephen King), will lead her up and down coastal Florida and beyond in a brand-new, whirlwind adventure, Mrs. Plansky Goes Rogue!

Mrs. Plansky is fresh off winning a thrilling senior tennis championship with her doubles partner, Kev Dinardo, and is gearing up to celebrate with him on his yacht. That is, until the yacht is destroyed in a fire. Kev claims the fire was caused by a lightning strike, pure bad luck, but there's one small problem—Mrs. Plansky didn't see any lightning.

Already certain there is more going on than what she's being told, Mrs. Plansky's curiosity turns to concern when Kev goes missing. Her suspicion gets the better of her and leads her to break into his house, only to find it ransacked.

But Kev isn't the only person Mrs. Plansky has to worry about. A conversation with her dad reveals that not long ago, he'd introduced Kev to Jack, Mrs. Plansky's wayward tennis pro son. And now, her dad—distracted by arrangements for his upcoming wedding—either can't remember or has no interest in divulging any details.

Worse? Now Jack has gone missing, too.
