Beckoning Blood (Bonds of Blood Book 1)

A gripping, blood-drenched saga about twin brothers, the men they love, and the enduring truth that true love never dies  -- no matter how many times you kill it.

Thierry d'Arjou has but one escape from the daily misery of his work at a medieval abattoir -- Etienne de Balthas. But keeping their love a secret triggers a bloody chain of events that condemns Thierry to a monstrous immortality. Thierry quickly learns that to survive his timeless exile, he must hide his sensitive heart from the man who both eases and ensures his loneliness...his twin brother.
 
Shaped by the fists of a brutal father, Olivier d'Arjou cares for only two things: his own pleasure and his twin. But their sadistic path through centuries is littered with old rivals and new foes, and Olivier must fight for what is rightfully his -- Thierry, made immortal just for him.
