Rules. Balance. Consequences. War. When Fate gave Dane the water from Eden to drink, she did more than save his life. She changed his destiny. Since the beginning, a covenant between God and Lucifer has maintained a tenuous peace, balancing Soulkeepers and Watchers and the natural order of things. Dane upset that balance the day he became a Soulkeeper. Fate broke the rules. Now, Lucifer is demanding a consequence, requiring Fate to pay the ultimate price for her involvement. God intervenes on the immortal's behalf but in order to save her soul must dissolve the covenant and with it the rules, order, and balance that have kept the peace. A challenge is issued. A contest for human souls begins. And the stakes? Earth. Winner take all. The Soulkeepers are at the center of a war between Heaven and Hell, and this time nobody, anywhere, is safe from Lucifer's reach.
