Harrowing Heights presents a classic and compelling storyline that is an excellent introduction to role playing games for DMs and players alike. With many parallels to popular video games, this adventure is an easy segway. The main plot contains plenty of intrigue and layered motivations that will keep players engaged and on their toes. The module is well-written and provides ample opportunity for customization with added suggestions, encounter and event tables, and an easy system for adding variety to combat. I didn't find myself leafing through pages often to find relevant information during play, it was right at hand. In addition, you receive a flushed out world with enough detail to be used independently or wrapped into your existing land. The cartography and artwork is wonderful and weaves inspiration and detail throughout the module. This adventure has all the needed pieces for a long-running campaign and you will not be dissapointed in your selection.
