Everyone’s favorite space rovers are back, this time facing a watery rescue operation!

Space explorers Rover and Speck are on a dangerous new mission: visiting Unexplored Planet K2-18b. It doesn’t take them long to encounter a frightening inhabitant - a blubber beast - or to find themselves inside its mouth! Luckily, they manage to escape unharmed. But when they learn that a local creature has been swallowed by the Beast, they know they alone can rescue him. They’ll have to go back in! Can they succeed? Or will they - gulp - get swallowed, too?

The fun is out of this world (even though they’re inside the belly of the Beast!) in this hilarious second book in the Rover and Speck series!
