Most Malhavoc products have a clean design, mostly B&W with reasonable white space. This makes them quick to read and lighter on toner. This one is no exception.
As a product:
This is a sourcebook covering possibilities of a deity dying, or being resurrected, and how to implement this into your campaign. Bearing in mind this is written by the author of the Planescape adventure Dead Gods, you can see Monte Cook recycling his ideas.
As is typical for this kind of book, there are new spells, feats, items, prestige classes and monsters. Most function around the concept that the body and soul of a deity have residual power that can be exploited. If you don't like the concept that dead gods can be carved up and used to fuel spells, you probably won't enjoy this book, as it doesn't offer much in the way of alternative approaches.
What it does offer is solid enough. Whether you like it or not will depend on how your ideas mesh with those presented here.
