From the New York Times–bestselling Goosebumps series, a tween boy accidentally turns back time on an antique clock and now every day he is year younger.

Tara the Terrible. That’s what Michael Webster calls his bratty little sister. She loves getting Michael in trouble. Making his life miserable. Things couldn’t get any worse.

Then his father brings home the antique cuckoo clock. It’s old. It’s expensive. And Dad won’t let anyone touch it.

Seems like the perfect opportunity to finally get his little sister in trouble for a change. But when Michael fiddles with the clock, hoping to make it look like Tara has damaged it, he unlocks a strange spell. A dangerous spell. A spell that causes Michael to get younger and younger and younger. . . .

Poor Michael. He should have listened to his dad. Because if he doesn’t figure out how to stop traveling back in time, he might have bigger problems than an annoying sister. . . .

A devious doctor, a secret laboratory, and a boy in a fight against time. And of course, magical Bubbles!

Benjay faces the biggest challenge of his young life. His magical Bubble friend Peepers has no idea of the danger that lies ahead as she breaks the rules to help her human friend. It’s the kind of danger that could impact all Bubbles. Mysterious events unfold, including unexplained improvements in Benjay’s condition and strange dreams of a woman who may be more than she appears. Join Benjay and Peepers as they face peril in their latest magical adventure!

Benjay’s Battle is a fast-paced adventure that blends elements of fantasy, science fiction, and mystery while exploring themes of friendship, curiosity, and hope in the face of adversity.
