The Blocker. The Shadow War

It's 1966 in Cuyahoga Falls, Ohio and teenager Arthur Earsterdrak is looking forward to the start of his senior year, until everything changes one fateful night when his sister is possessed by something dark, something evil. In a desperate attempt to free his sister from the clutches of a shadowy entity and fearing that they won't survive the terrifying encounter, Arthur's destiny is revealed as a power within him awakens.
It will draw him into a hidden conflict that has raged for centuries, over multiple dimensions, where the very soul of mankind is at stake. Arthur might be the answer that the Alliance of Worlds has been waiting for, as he joins the fight with heroes from other worlds, including Zeus, Odin and Ra. These legends have fought the Shadows throughout recorded history, but if they have any hope of defeating the Shadows, they need a Blocker, a champion who can use the light to destroy this dark evil.
The people Arthur cares for, his family, his new allies, and the girl he believes he is growing to love, are all in danger of losing not only their lives but their very souls. And it is up to Arthur to learn how to use his new power before it is too late.
