Infinite Sacrifice (Infinite Series, Book 1)

Maya's shocked to discover it's not the heaven she imagined;in fact, a life of adventure begins the moment you die.
Zachariah, her faithful spirit guide, explains the rules of the dead: in order to regain complete awareness and reunite with loved ones all souls must review their previous lives.
Maya plunges warily into her turbulent pasts as a sociopathic High Priest in ancient Egypt; an independent mother protecting a dangerous secret in glorious Sparta; an Irish boy kidnapped and enslaved by Vikings; and a doctor's wife forced to make an ethical stand in plague-ridden England.
All the while, Maya yearns to be with those she cares about most and worries that she hasn't learned all of heaven's most vital lessons. Will she be forced to leave the tranquility of heaven to survive yet another painful and tumultuous
life? Or worse, accept the bitter reality of having to go back alone?
