A doomed version of Havana, monsters hunted for cards, and a spider goddess stalking Carl across the whole floor.

After the bleakness creeping in through books four and five, this one brings the irreverence back without giving up the weight. The action is the most unhinged in the series to that point and the character work keeps pace with it.

It ends on a plan of Carl’s that is pure series logic: find the loophole in how the floor was designed, then exploit it with a giant demon.
