Summoners' Keep: The Red Horn Saga (Book 3‪)‬

Summoners' Keep is the third book in the Red Horn Saga, an epic fantasy that skillfully blends high fantasy, steampunk, Cthulu, and space opera. The magic is unpredictable, the spaceships run on coal, and no power known to dwarf, elf, or man can stop the carnage. Only a hero small enough can save us now.
