Apocalypse Meow (Movie Club Mysteries, Book 7)

"My descent to the Seventh Circle of Hell began with a lawn chair."
When Maggie loses a lucrative contract for her P.I. agency due to an accidental full frontal flashing, she's forced to accept the only other job on offer: one involving her nemesis, the pampered show cat, Quibbles. Maggie and her wacky associate Lenny are hired to escort Quibbles to the final round of auditions to become the face of a luxury cat food brand, Purrfect Paws.
Instead of the five-star hotel they were promised, Maggie and Lenny find themselves trapped in a run-down hostelry in the middle of a hurricane. To make matters worse, their fellow guests include five spoiled celebrity cats and their ruthlessly ambitious owners, all of whom are determined that their cat should be chosen as the face of Purrfect Paws.
And then a cat-astrophe strikes. One by one, the owners start dying. With the storm raging, and the body count rising, Maggie and Lenny are determined to find the killer before their inn turns into a morgue.
