Zelazny moves [in Roadmarks] from sword-and-sorcery to a literary time-travel/quest frolic that's only slightly less giddy than the hijinks of George Alex Effinger…. A confusing, meandering lightweight—but Zelazny's bright imagination and wry wit are in top working order; so readers who fancy erudite diversion may want to travel this road, even if it goes nowhere in particular.
