The World Tree. The Saga of Þolgóði, #3

Tyr Þolgóði has lost the power that once made him feared. Stranded without the lightning of the Æsir and haunted by everything Jötnarland took from him, Tyr must return to a world already beginning to fracture. His enemies are gathering, old alliances are failing, and the truth behind his birth is drawing him toward the one place no mortal was ever meant to reach... the World Tree. As the boundaries between realms begin to break, giants, gods and men are pulled into a war that will decide far more than the fate of the North.
To survive, Tyr must learn who he is without his power, confront the voice within him and uncover the price of the bargain that shaped his life before he was born. But the World Tree holds truths older than the Æsir... and some truths were buried for a reason. With every realm threatened and those he loves caught in the coming storm, Tyr must choose what he is willing to sacrifice to restore what was lost.
To save the world, he may have to become the very thing he was raised to destroy. The World Tree is the third and final book in The Saga of Þolgóði, a dark epic fantasy of Norse-inspired mythology, ancient powers, brutal war and one warrior's final battle against fate itself.
