The Pact by Joshua Nye

Virgil is a man on borrowed time. Haunted by the horrific death of his mother, he was entangled into a fate-altering pact with a heavy cost. In exchange for half of his life, Virgil received extraordinary powers to control spirits and aspects of life itself. However, these very same abilities alienated Virgil and caused him to withdraw from others. Now, Virgil's path will lead him down a strange and perilous path against a series of fearsome enemies. Along the way, Virgil will meet a strange cast of friends from distant lands. Together, they will fight cultist zealots, unspeakable monsters, and much worse in a bid to save the Earth from the coming doom. Can the Earth be saved? And what secrets lie in Virgil's lineage?
