As bloody battle rages on between the two surviving dinosaur kingdoms, Eleri and his fellow outcasts, newly exiled from their herds, are searching for evidence to prove a mass conspiracy--a conniving cabal of carnivores have manipulated the herbivore kingdoms into war, so they can feast on the slain. But after their temporary home is discovered by a vengeful pack of raptors, the exiles must flee and soon find themselves trapped inside the Fire Peak: the volcanic heart of the dreaded Carrion Kingdom.

Before they have a chance to escape, they discover a cavern of imprisoned herbivores, who are being picked apart--literally--one by one. Can the outcasts stage an elaborate heist to free the prisoners and gather proof of the Carrion Kingdom's vicious plans in one fell swoop?
