Theology and science mix like oil and water. Never in his life would Eris Vandermere have thought The Effect of Divine Presence on Human Behavior would be the topic of his final research paper of the year-yet he finds himself combing the city streets with sophomore Miri Chase, tracking the footsteps of a real-life god who walks the mortal realm.

When the God of the Sea rescues a child from certain death, his divine blood heals the child's wounds, and the mortal world hails him as a hero. An undercurrent of intrigue among the mortal population grows and slowly festers, which leads Eris and Miri to stumble across a horrifying truth: mortals will do anything to get their hands on God's Blood.

What starts as a simple school project morphs into a frantic scramble for human survival. What must one do to appease an angered god? And how far is a god willing to go in the name of justice?

After all, nothing is more devastating than divine rage.
