When his body was hideously damaged in an enemy attack, it looked as though Inquisitor Gideon Ravenor's promising career would be abruptly brought short. Now, encased in a life support sytem that keeps him alive but forever cuts him off from the physical world, Ravenor utilises his formidable mental powers to continue his investigations. Along with his retinue of warriors and assassins, Gideon Ravenor fights to protect an Imperium he can no longer see, hear or feel.
A wonderful book and very fast paced, but I have to say that in Dan's usual style, the plot is revealed and only truly picks up somewhere halfway through the book. I like how different Ravenor is from Eisenhorn, and it felt good running into some of the familiar characters.
One thing I have to say is that I would not recommend this book as an entry point into Warhammer 40k because it's jammed chock-full with terminology and Dan's own elaborate vocabulary that someone entirely new to the setting might get confused (and admittedly for 1/3 of the book I was as well).
Other than that - a wonderful addition to the personal section of Warhammer worldbulding that Dan is still developing.
