Fans who were disappointed by the Heroes V game manual might be tempted to pick up the Official Game Guide published by Prima. According to Sir Charles at The Genies' Lamp, that would be a mistake. While he admits that he found previous Prima guides useful, including the one for Heroes III, he describes the Heroes V guide as a "worthless piece of rubbish." It includes information that has been on fan sites for a very long time, sections similar to what can be found in the game manual, blurry screenshots, and stats and tips from the beta. The author of the book did a better job with the artifact, walkthroughs and adventure map locations, but that probably isn't worth $20.
