World of Frem e-bog

Frem, a quiet little man, goes on an Odyssey to find help from four other villages that are also regularly attacked by Cajjh, the leader of a raping, pillaging tribe of people. To do so, Frem had to escape the trees that had created an impenetrable wall around his own village, travel through the desert and travel down an underground river where he meets a girl with a pet protector, a tiger.
