“I dont remember reading anything of Joel Rosenbergs.”
His SF includes “Not For Glory” and “Hero” — about the Metzadan Mercenary Corps, military SF. His fantasies include the Paladins series and the Guardians of the Flame series (although the latter series are more fantasy parodies - like Mike Resnick’s “Stalking the . . .” books).
