Karl Bear and Joseph Mendoza are two men who have never met. Both fighting their own demons, these men have no idea they're battling for their souls. The gods have chosen them for a divine experiment. Both are the products of reincarnation, and their souls once belonged to two significant, historical figures. Born in the same time and place, what effect will they have on each other? All humans have emotional baggage, but do souls? Do the circumstances of past lives haunt both men? Is evil passed on? Is good? After the men are brought together through a tragedy involving a woman named Emily, a divinely ordained collision may reveal the answers.
