This is the third volume to showcase the stylized stick-figure adventures of the Order of the Stick, a group of sometimes inept and always quarreling swords-and-sorcery adventurers on a quest to defeat their arch-enemy and, of course, obtain wealth and power along the way. The previous two volumes ("Dungeon Crawlin' Fools" and "On the Origin of PCs") were a collection of the first installments of the web comic and a batch of new material to provide character backstories respectively. This present book carries on the plotlines introduced in the first collection. (OOTS also appears now in "Dragon" magazine as a series of one-shots strips that do not pertain to the ongoing story.)
These collections are HIGHLY recommended to any D&D player (especially those familiar with the 3rd Edition rules) or to any fantasy RPG fan in general. The strips feature side-splittingly wry humor, actual character development, worthy and interesting opponents with intricate schemes, recurring NPCs, and nifty adventures. (And, as a bonus, there are almost no typos or grammar errors such as plague almost every other web comic.)
Mr. Burlew provides some authorial reflections in different sections of the book and some hints about what is yet to come (he is projecting a five-to-seven book series before OOTS wraps up). There's also some previously unpublished material included.
High page count and quality paper, too.
Pick this up immediately, and then order a copy for your closest friend.
