Disclaimer: I have read the entire adventure, but have have not run my group through it yet. Unlike the Death House, there is no down time and the players are dumped right into the action. It seems a bit hard on the surface for the advertised character levels, but many of the encounters are avoidable. I really liked the tips from the author interspersed throughout the pages. Even though the goal is just to escape, there are a few follow-up adventure hooks based on things the players may find. Overall I give it 5d20 out of 5d20 and plan to run my group through it this weekend.
