The Wolf Age by author and reviewer Tim Pratt. He calls The Wolf Age "inventive and delightful," and says, "Enge's plot is admirably twisty, and he keeps things moving with impressive set pieces, werewolf battles, bizarre magical airships, miraculous feats, and liberal doses of skewed humor. One of his great virtues as a writer is weirdness -- he's not afraid to do the unexpected, and his imagination is formidable. But there's an underlying emotional power here, too. The author excels at depicting the bonds of friendship, the pain of betrayal, and the tragedy of well-laid plans going awry, and that emotional payload is what makes this novel into more than just an entertaining adventure story about a guy with a magical sword who fights monsters. Enge is one of the most engaging of the new sword and sorcery authors, and I hope we get to follow Morlock's exploits for a long time to come."
