Atlantia is all but destroyed and Titus dethroned. Hopper, Zucker and Firren are working hard to rebuild, and as the liberated refugees flood the tunnels the process of reorganizing begins.
But life is difficult...Queen Felina, the evil feral royal, is amassing a new band of street cats and, without the sinister "peace accord" in place, it's open season on the rodents. Pinkie and Pup have left for the safety of the Mus tribe, where Pinkie has led a coup of her own, disbanding the tribunal. Removed from power, Sage of the Mus is seeking to reclaim his title, but Pinkie is ruling with an iron paw, claiming to be fulfilling La Rocha's prophecy. And Pup - he's no longer the sweet, innocent brother Hopper once knew.
With new upland allies, including a funky cat named Ace, can Hopper make the tunnels safe again and fulfil a destiny he never imagined?
