I never ran the adventure but I did read it, dont remember it being anything special. I also read the Sea of Fallen Stars campaign supplement that came out about the same time and it was great I highly recommend it. I ran an undersea campaign around then and the biggest challenge was giving the PCs the ability to breath underwater without it being too easy, i.e. heres 60 scrolls of water breathing or 5 necklaces of adaptation. The Threat From the Sea trilogy of novels were pretty good too.
