Created by Ashlings World, who have had experience in creating other guides for Warhammer and World of Warcraft, so the guide is well written and edited to high quality.
Within its 96 pages, there are detailed maps of zones and instances and nearly all NPCs. Also the number of pages constantly increases over time through updates which are free. The current version is 2.0.
In addition the guide comes complete with map waypoints, which is useful for those of you that have had problems with alt-tabbing in the past.
