You've heard of the Rescue Rangers. Now meet the Mouse Watch.

Six months into their Mouse Watch training, Bernie and Jarvis are getting along like cheese and crackers! Less exciting: having already completed their first successful mission, it's now back to basic training.

But more pressing matters are at hand (or rather, at paw). The remains of the S.S. Moon, a long-lost spy vessel, have been found. Onboard the ship is a legendary map, and the transmission says that it leads to an energy source that could save—or destroy—the planet. The Mouse Watch must get to it before it falls into the clutches of their nemesis, R.A.T.S!

Bernie and Jarvis suit up—in scuba suits, this time—for a deep-sea mission on a submarine the size of a shark-snack. Their mission brings them whisker to whisker with a giant robotic kraken, nefarious R.A.T.S. agents, the underwater city of Cat-Lantis, and more underwater perils, all in a fight against time to keep a powerful weapon out of the clutches of evil.

"Mice in Black" meets "Mission Im-paw-sible," this high-octane follow-up to The Mouse Watch will appeal to fans of the tiny rodent heroes, as well as draw new readers in with adorable antics and high-stakes adventure
