What did you like about the book?  In this latest installment of the My Pet Slime series, Piper, her time-traveling grandmother Sadie, Cosmo the slime, and Piper’s best friend Claire are kidnapped and stuck in a cell at MaLa, a dangerous corporation. The adventure and mayhem are reminiscent of a Scooby Doo episode with nefarious adults and meddling kids. Piper and the crew must navigate betrayal by Clare’s Uncle Ricky, escaping from their jail cell using origami, sliding down a long and twisty slide, a motorcycle race, and a rocket launch to Jupiter. Adding to the stress is the fact that Cosmo is sick. His color is fading and Piper feels the only way to save him is to send him to Jupiter. Thankfully, Cosmo is on the mend by the end of the story, ensuring readers will see more of him in a future book. Each chapter is concise with colorful, engaging illustrations, and the book provides just the right amount of suspense. The end pages detail additional information about Sally Ride, origami and Space X which are featured in the plot of the story.
