The Deadlands: Trapped

As bloody battle rages between the two surviving dinosaur kingdoms, Eleri and the other young exiles—including a peppy stegosaur, a stoic sauropod, a testy triceratops, and a mysterious spy—search for proof to convince their herds that the war is a setup orchestrated by the secret Carrion Kingdom, a conniving cabal of carnivores determined to feast on every living herbivore. But without evidence, not a soul believes them.

Chased out by their own families and pursued by raptors, the exiles flee into the treacherous Deadlands only to find themselves trapped inside the Fire Peak: the volcanic heart of the Carrion Kingdom. When they discover a cavern of imprisoned herbivores, the outcasts must stage an elaborate heist, bring down a tyrannosaur general, and gather the proof they need in one fell swoop.
