The Lord of Darkness has set his sights on total multiversal conquest, tearing through the boundaries between worlds one by one.
Caught in the middle of the escalating chaos is Rem Worthswords — a brilliant, selfish, and morally gray detective who wants nothing to do with heroics. Dragged reluctantly into the fight alongside a scattered band of true heroes, Rem refuses to see himself as one of them. But as the war between worlds intensifies, even a man who trusts no one but himself may find he's the only one sharp enough to outthink a god of darkness.
