Oh my god Divine Power is a very cool book. Although not officially released until next week, I have a copy of Divine Power now. It provides new powers, feats, paragon paths and epic destinies for divine classes as well as introducing new rules for divine domains. If you play a divine PC you need to get this book.
The first four chapters are dedicated to the four divine classes. Contained within each is exactly what you expect: new builds, new powers and new paragon paths. Here are the highlights.
