Deathwatch: The Last Guardian: Warhammer 40,000 (Unabridged‪)‬

As part of an elite Deathwatch kill team, Brother Balthasar of the Dark Angels joins a special Inquisitorial mission to the eldar craftworld of Kher-Ys.

Long ago ravaged by the daemonic forces of Slaanesh, the craftworld may still harbour the unlikeliest of allies for the Space Marines and the key to a greater victory for the Chapter.
