It's Marlowe Middle School's big sleepover, and the Bubblegum Shoes detectives must race to solve a blackmail case before lights out. From the New York Times bestselling author of Kill the Boy Band comes the second installment in this whip-smart, crime-solving series.

Crime doesn't sleep...luckily neither do they.

Normally, Maya Mendoza wouldn't be caught dead at school on a Saturday, but it happens to be the most epic night ever: Marlowe Middle's big sleepover! The Bubblegum Shoes detective agency is taking a night off from solving cases to enjoy the Battle of the Bands, the all-you-can-eat candy, and the limited adult supervision...or so they thought.

When the girls learn classmate and rising YouTube star Hunter Holloway is being blackmailed to drop out of the singing competition, they have to help. But what was supposed to be an easy case quickly turns complicated when the Gumshoes discover an illegal pillow-fighting ring, battling Broadway divas, and counterfeit art--not to mention Hunter seems to be hiding a few secrets of his own.

Can these slumber party sleuths solve the case before the fun is over? Or will this sticky situation spell lights out for Hunter's career and the Bubblegum Shoes' reputation?

A smart, sharp, and sensational second book in New York Times bestselling author Goldy Moldavsky's middle-school mystery series.
