Shadowphoenix: Requiem

Markus Latimore is not your usual vampire. Living in San Antonio with his human wife, he had perfected the masquerade he had been trained to live since birth. As a practicing occultist, he dedicated his days and nights to helping others and loving his wife.
One favor for a friend changed all that.
Within hours, his wife had been attacked, and his carefully orchestrated world began to crumble around him. Now, he must navigate a murky labyrinth of deception, duplicity, and death. Innocent lives hang in the balance, and he quickly learns that the stakes he's playing for couldn't be higher. To survive, he will have to do the unthinkable.
For the first time in his life, he will have to fully embrace his vampiric nature. If he fails, there will be hell to pay. If he succeeds, the shadow world in which he moves will demand his death. Either way, he'll have to give the devil his due...
