The book is split into 2 different time periods which are obviously connected but it doesn't become apparent until midway through.

Also it has a major plot twist which affects not only the book but the entire history of 40K. This is the main reason why i believe it is a must buy for anyone interested in the story line to the game. If you aren't then this book is still a great read i couldn't put it down so get it ordered.

Very, very informing

The book centres on a Dark Angels Interrogator Chaplain who doubts his faith in his chapter. After discovering the presence of "The Fallen" in the system he is posted in, he immediately launches a crusade to bring them to justice. Over the course of the book we are taken back to one of the Chaplains early interrogations, a man who was a previous Chapter commander during the Great Crusade. Here he divulges why it was he who started the civil war in the Dark Angels ranks, but not because he was disloyal, but because Lion El'Johnson, the Dark Angels Primarch, harbored a dark flaw that would bring his chapter to damnation. The book flicks back and forth in time, following the interrogation of the chapter commander as it proceeded and the crusade to hunt "The Fallen". Over the course of the book we find out the "truth" behind the Dark Angels long harbored secret.

A must have book for any follower of the Dark Angels, Space Marines, or anyone else interested in the history of the Warhammer 40,000 Universe. A thoughrally entertaining and informing book. Stun your friends with your new found information about the Dark Angels, or just satisfy your own curiosity.
