Thousands of years ago, a young warrior slayed a Nephilim with a sling, some stones...and God's help...In modern day, Achava is the warrior. The avenger. And now, a wife. When Achava, supernatural guardian of Israel, marries Professor Sam Godfrey, she loses some powers. Becoming more human by the hour, Achava can no longer Soul Merge and must rely on her half-sister, Anthea, for such travels. Sam doubts Achava can battle evil without her supernatural abilities...Just as Sam packs up the ancient sling and supplies for their honeymoon, a familiar foe attacks them. In her haste to save them, Anthea does a Soul Merge, but she finds it impossible to carry both passengers. When Sam finds himself stranded on a frozen mountain, he's alone. In this forsaken place-and without his beloved bride-Sam's faith and spiritual knowledge will be tested. But even if he passes one test, more will come, until Sam faces the greatest test of his life...
