Sorry for the vote, I really like RoC but this adventure is meaningless. You can describe it as a random set of encounters without rolling on Random Table, encounters including also: Nyogtha, Deep Ones a Children of Yig.
The adventure has a good start with a simple but nice outline a solid background and a high quality description of Dark Harbor (location pretty much useless for this adventure) after that the adventure follow the path of boringness and, as a master, it is a difficult task try ti add some sense in the adventure.
Supporting cast descriptions and creatures are very well done and can be useful for other adventures. A big missing are some pregenerated characters. Layout and editing are perfect and the price is fair.
I truly hope in more products for RoC, and I really recommend the Core Rulebook of Realms of Cthulhu, will be an improvement for any Cthulhu Role Play Games.
A pragmatic fan.
