Lifetimes

'As he looked on in horror, the woman turned her head, giving Craig the full view of the exit wound. A piece the size of a grapefruit had been blown out of her skull. What remained within was black and lifeless.'

Lifetimes is the sequel to Legacy, the story of time-travelling ex-Marine Craig Edmonds, and his battle to save himself and his family from the evil witch, Beyath. 

Able to harness both time and space, Beyath returns from the dead to hunt down Craig Edmonds and destroy everything he knows and loves. Trapped in an alternate timeline, with no wife or family to support him, Craig is a wreck and bent on self-destruction. But with the help of a friend from his original lifetime, he slowly comes to terms with his new reality, and the two of them decide to go back to 1968 to finally destroy Beyath, not just in one timeline, but across all timelines. The question is: will they succeed?
