This book is the ultimate reference for the game. The book is extremely thorough and very detailed. The text and images in the book are clear and the addition of the large map a welcome bonus (as is the Dragonborn bookmark – a nice touch). The book covers the three official add-ons (some earlier releases don't). Read it like a manual, or dip into it as a reference book when you're stuck. Either way, it will enhance your enjoyment of the game.
