A third-party sourcebook on trolls for D&D 3rd Edition. This includes details on biology and culture, combat tactics, roleplaying tips, troll variants, rules for troll characters (including unique feats and spells), adventure hooks, and a sample troll settlement. The book is well-written overall, and does have some neat ideas here and there, such as creative uses for troll regenerative abilities. However, much of the book doesn't stretch far beyond the core troll, and this is especially noticeable in the tactics and roleplaying sections. The section on variants was also disappointing, as the variations were pretty limited. (Originally posted on Goodreads)
