Last Barbarians Vol. 1 [PDF ebook] 

In a world where your guild means everything, classless Sylv is labeled a Barbarian. She’s a jack of all trades who can fight, pick most pockets, and cast a spell or two. But without official membership to a guild, she’s barred from having adventures. No adventures means no money, and no money makes it awfully hard to support herself and her 7-foot-tall disabled brother. But when an underhanded cleric says he’s got the quest of a lifetime for her, she can’t really say no (even if she knows she should). It’ll take every skill she’s got to stay alive, save a child, prevent the fabric of the universe from being ripped apart, and prove that being multiskilled isn’t totally barbaric.
