Time for another review of Wizards of the Coast's Original Adventures. For a while it seemed like Owen K. C. Stephens had been holding the series up single-handed, but now Skip Williams (one of the D&D 3e designers) takes the reigns with
Cave of the Spiders for 9th level characters. Originally designed for D&D 3.5, the
Cave could be played under the Pathfinder rules or another D20 system without too much trouble. The window of opportunity to pick this adventure up free has closed, but $0.99 will get you a copy of
Cave of the Spiders.
