Lone Wolf: The Horus Heresy Series (Unabridged‪)‬

As daemons swarm across the fields of Velbayne, bringing madness and Chaos to all that they touch, Leman Russ and the Rout stand arrayed against them. Packs fight back to back, brothers protecting one another - except for one. The Lone Wolf, the warrior without a pack, stands alone. And somewhere on the battlefield is a foe against which he will have vengeance.
