In The Lost Book of B, the immortal warrior becomes a pawn of none other than Genghis Khan himself, the brutal warlord of the Mongol Empire. As the berserker is used as a pawn to destroy, devastate, and pave the way for the Silk Road, he must battle against his seemingly unstoppable violent urges and break free from the hold the warlord has over him.

In A Faceful of Bullets, B. finds himself in the snowy wilds of Pre Civil War Missouri, and caught up in the conflict involving a land baroness's father and an abolitionist. After a deadly series of events, he's mistaken for an angel, one to be used for vengeful purposes. While B. insists that he's no angelic figure, it's only a matter of time before the truth is revealed to those involved...
