"Two lovable mismatched rovers are back for another adventure, this time on an oceanic planet! Organized, careful Rover and impulsive, excitable Speck are ready to set off on their next dangerous, hazardous, mysterious mission: a trip to Unexplored Planet K2-18b. Adventure is underway as they splash down onto the watery surface of this world and get to know the locals. Before long, the two rovers find themselves on a new mission: to help two Spikey-Spikes recover their missing brother from inside the belly of the terrifying Blubber Beast! Will Rover and Speck be able to outwit the Beast and save their new friend? Or will they get -- gulp -- swallowed up too? Jonathan Roth's hugely appealing graphic novel combines classic comic-style art with a gripping plot, loads of extra-silly laughs, and two endearing characters to root for. It's also a great introduction to real rovers and robots, and the entertaining science sidebars sprinkled throughout the story give readers a chance to learn about marine biology, ocean creatures, and more. Backmatter includes a drawing lesson ready-made for classrooms and a fun spot-the-differences activity. This winning combination of accessible STEM content, perfectly kid-friendly humor and loads of adventure is sure to satisfy armchair astronauts everywhere"--
