The First Technomancer (Vazanklav Book 1)

Born at the end of Earth's days, Drake Frost was not one to see his world's end. He did, however, survive it - in a way.
In a world and time where The War is far, Drake finds himself alone, standing beside his gravestone, free in a prison of incredible scale. The time he lived and died for has long gone, yet he remained, a lone remnant of what once was.
The warriors of this new world are strong, but little can match the raw might of a Corporate engineer of old.
