Smored

the long version

"After her grandfather gifts her a relaxing weekend at his luxury cabin, Lacey packs her best friend Meg into the Lumina and together they take off, dreaming of a girls' weekend filled with bonfires, boat rides and work-free days. However when 3 unexpected visitors show up on the doorstep of the Luzzi cabin, her plans of peace and quiet are foiled. It only gets worse after Lacey finds a dead body in her trunk -- with no explanation as to how, or why, he'd landed face down in her leftover Taco Bell! Suddenly, Lacey's trip is no longer a weekend getaway, but a top secret assignment full of kidnappings, karaoke bars, and a suspiciously meddlesome grandmother. She recruits the help of new boyfriend Anthony as well as computer whiz cousin Clay, and together they must find the murderer, or else they will be planning a very different kind of getaway."--
