The stakes are higher than ever; the destiny of the dinosaurs is uncertain in the third book of the Dino Trouble series. Amateur paleontologist Mr. Smith and his young neighbor Johnny team up once again after discovering a ring of dinosaur hunters and their secret jail- which houses dozens of captured dinos. The hunters earn Johnny and Mr. Smith's trust with the promise of opening a Dino Park where the giant creatures can roam freely and have plenty of snacks, and the duo then convinces free dinosaurs to surrender willingly. But behind the promise for a better life hides a sinister intention. When Johnny discovers the hunters' true goals, the plans shift abruptly.
