To those familiar with science fiction, the recent work of Roger Zelazny must be considered something of a letdown…. Mr. Zelazny has not been especially popular these past few years. But with Roadmarks, his latest, there is reason to believe that his writing has regained the depth and fluency that have not been apparent for so long.

Roadmarks is written in the typical Zelazny style, which is often hard for an inexperienced science fiction reader to follow at first, but which reveals itself in later readings to be succinct and flowing….

In terms of being a science fiction "mystery," Roadmarks is excellent, and it makes use of the "trick ending" method as well as any recent work. Readers concerned with hidden messages and allegories will find it loaded, and its appeal should cover both the "hard" and "soft" audiences of science fiction quite well.
