The tawny cat's master plan
The evolutionary journey of the Barque Cats continues as the refugee cats seek asylum on Pshaw-Ra's planet, Mau, a world of ancient secrets and advanced science that Pshaw-Ra declares will bring about his goal of feline domination of the universe! Can Jubal and Chester stop the tawny cat's master plan? Do they even want to? Wouldn't cats running the universe actually be a good thing? Watch for Catacombs, the next in the Barque Cats series, coming from Del Rey.
