Land That Time Forgot Book 1

Hidden behind towering, impassable cliffs, Caspak will not easily give up its secrets. Unique and terrible animals and peoples inhabit the island. Dinosaurs terrorise tropical jungles to the south, while menacing winged humanoids dwell in cities on a large island in the north. Caught between these threats are scattered groups of human beings. Despite their differences, however, Caspak’s animals and peoples are all connected in a mysterious and marvellous way.
