One of Sharp's five top books about trolls, as shared at Tor.com:
The Hobbit by J.R.R. TolkienRead about another entry on the list.
I almost skipped this one as it seemed too obvious—to be honest, it was the Rankin Bass cartoon version more than the book itself that so profoundly spoke to early me—but to omit it would be inauthentic to my trollish thinking. Three Stone trolls, Tom, Bert, and William Huggins, capture and discuss the eating of our fourteen heroes after a botched burglary attempt. These trolls are once again pretty dumb, but they make quick work of what are supposed to be an elite collection of dwarves who are only saved by the last minute cleverness of the Wandering Wizard. (The aforementioned savagery and greater fantasy world context for the trolls in this one showed me, and us all, the scope of what trolls, at their brutish best, could be. They had names, clothes, personalities, and a cave full of ancient booty. There was a treasure trove of unexplored myth there as well.)
