Better book than expected, at least it was clear with a normal narrative, not like other books in this series. I feel however that it started some narrative threads that will not be continued, and would be interesting. ( )

This entry into the Horus Heresy series focuses on primarch Corax and the Raven Guard and how they barely escaped from the Isstvan massacre with less than 5% of their original numbers. I was grateful that the Heresy authors finally produced a novel that really focused on the core issues of Horus betraying the Emperor and how other primarchs (Corax in this case) reacted immediately after. Especially riveting is Corax's direct interaction with the Emperor himself, and how the Emperor plants the seeds of retribution into Corax's mind. What follows is Corax's attempt to acquire the gene-tech material the Emperor used himself to create the primarchs to rebuild the Raven Guard, and the traitorous Alpha Legion infiltrating the Raven Guard to destroy any attempts at rebuilding. This novel also offers hope to fans of the Emperor and his reign on Terra in describing how Corax/Raven Guard set themselves back on the path of revenge and retribution. One of the better Heresy novels since the original Heresy trilogy.... ( )

In Deliverance Lost you are introduced to the Raven Guard and their Primarch Corax. Unlike some of the other editions in the Horus Heresy Corax is a main character in the book. You follow the Raven Guard after their near annihilation on Isstvan V back to Terra and then back to their home on Deliverance as they try to rebuild the legion in order to take the fight back to Horus. But they do not know that they have been infiltrated by operatives of the Alpha Legion who plan on finishing the job that was started on Isstvan. In this edition you get to read some more about the Emperor, the Twin Primarch's of the Alpha Legion and some brief appearance's of Dorn and Horus. A good book, but I tend to get frustrated with some of the seemingly dumb decisions that the legions and Primarch's loyal to the Emperor keep making. ( )
