I expected that this PDF would give me the game stats for a lich to use in a Pathfinder game, and given the complexities involved in running a lich, that in and of itself would have been money well spent. However, in addition to the lich (who has levels in the alchemist, wizard, and loremaster classes, making it a very complex stat block indeed!), we also get stats for four other undead NPCs: an aristocrat ghost, a juju zombie ranger, and two types of wight, one with rogue levels and one with levels as a sorcerer. As their backstories are all interrelated, a GM can build a series of encounters with these creatures in an extended adventure or even over the course of several adventuring levels, as the NPCs range in CR from 2 to 16. (And if you're not one to create your own adventures, all of these NPCs are suitable for a related product, the 64-page adventure "The Sinister Secrets of Silvermote," written by Richard Hunt, the same author as this product - and a semifinalist in last year's RPG Superstar contest).
Besides the NPC stats, the product also contains a new spell developed by Temerlyth the lich (in his days before lichdom) which ties in with his motivation: destroying lycanthropes wherever they may be found.
There's some excellent artwork depicting Temerlyth the Undying, his ghost bride, and the juju zombie he created from the body of his wife's lover. Furthermore, links abound in the PDF, making this exceptionally easy to use in electronic form during a game session. This is the first TPK Games product I've seen to date, but count me impressed!
