Very good short adventure. The story is quite creative, the encounters are well described, with tactical maps easy to convert with ground tiles or an erasable battlemat, and there's two well thought skill challenges that have a real impact on the adventure. I ran it two times with different groups, and both were a little frightened by this strange spider story !
Maybe more precise descriptions of the monsters would have been an interesting addition, but for the price it earns easily five stars still.
