Here's an idea: Perhaps they should be read together as unofficial companion volumes.
However, while we're talking about the contemporary heirs of the sword & sorcery mantle, we must give shout outs to Saladin Ahmed, Howard Andrew Jones, Violette Malan, Ari Marmell, Jon Sprunk, Michael J. Sullivan, and Sam Sykes. Likewise, R. A. Salvatore looms large in the field, and I've been very impressed. I've also been mightily impressed with the Pathfinder Talesline of tie-in novels, and much of the short fiction appearing on the e-zine Beneath Ceaseless Skies. We are in something of a renaissance for sword and sorcery. Long may it continue.
