SeaJourney (Arken Freeth and the Adventure of the Neanderthals) (Volume 1)

Part Neanderthal, but raised as a human, Arken Freeth finds that he doesn’t fit in either world as he struggles to survive.
Arken Freeth has always wanted to prove himself worthy of his king’s appointment by becoming an officer in the Lantish Sea Service. Now the only thing standing in his way is his apprenticeship SeaJourney. But a peaceful training mission soon turns into a deadly struggle for survival as Arken’s fleet must come to the aid of a princess fleeing capture by Tookan pirates.
Arken sets sail 13,000 years ago from Lanth, a lost civilization on the old coast of Florida. Mankind survives in high-walled cities in this world of forests infested by giant bears, sabertooth cats, dire wolves, and an ocean roamed by giant sharks. He leaves home with his bow, his honor, and a deadly secret he must never reveal; he will never truly fit in, because he is not completely human. The blood of Neanderthals runs through his veins in a land where marriage to Neanderthal slaves is punishable by death.
Yet the very Neanderthal heritage that makes Arken an outsider gives him extraordinary strength and fighting skills. In order to survive and become the warrior he knows he can be, Arken must brave the dangers that lurk beneath the depths of the Circle Sea, the old Atlantic, as well as the Tookan pirates who roam its surface.
A new adventure series for those who loved series like Eragon, Percy Jackson & the Olympians and Harry Potter.
