Thy Father's Shadow: The Sanctuary Series, Book 4.5

The world of Arkaria is a dangerous place, filled with dragons, titans, goblins and other dangers. Those who live in this world are faced with two choices: live an ordinary life, or become an adventurer and seek the extraordinary.

In the depths of the dark elven homeland of Saekaj Sovar, Terian Lepos returns home after a long estrangement from his family. Separated from his friends in Sanctuary, Terian must reconcile with his father in order to keep the family's honor from a threat brought forward by an old enemy. Faced with test after test that strains him to the breaking point, Terian must discover for himself that the line between loyalty and betrayal is thin indeed...and that sometimes, the sharpest knives are wielded by those you know best.
