Silver under nightfall - Rin Chupeco

Remy Pendergast is many things: the only son of the Duke of Valenbonne, an elite bounty hunter of rogue vampires, and an outcast among his fellow Reapers. Though the kingdom barely tolerates him, Remy has been shaped into a weapon.

When a terrifying new breed of vampire is sighted outside of the city, Remy prepares to investigate alone. But then he encounters the shockingly warmhearted vampire heiress Xiaodan Song and her infuriatingly arrogant fiancé, lord Zidan Malekh, who may hold the key to defeating the creatures. When he's offered a spot alongside them to find the truth about the mutating virus, Remy faces a choice - one he's certain he'll regret.

But as the three encounter dangerous hardships during their journey, Remy develops fond and complicated feelings for the couple. He begins to question what he holds true about vampires. Remy must decide where his loyalties lie: with his father and the kingdom he's been trained all his life to defend or the vampires who might just be the death of him.
