Imitate the Dawn by M.A. Grant

There’s a thin line between love, hate, life and death in this vampire bodyguard paranormal romance from M.A. Grant, author of The Prince of Air and Darkness.

Cristian Slava and Atlas Kincaid despise each other. At least, that’s what they need everyone to believe. In truth, the charismatic vampire and his fierce bodyguard are more in love than ever. But when a powerful political faction emerges and threatens Cristian’s family, the only way into their enemy’s inner circle is without each other by their side.
From Romania to New York and beyond, though apart, their blood-bond cannot be severed—but it can be used against them. When Cristian sacrifices his life to save his family and save Atlas from having his darkest secrets revealed, only faith in that bond will keep Atlas from utter despair.
And only by facing his past will Atlas be able to accept who he is and finally defeat their most powerful enemy yet…
Death itself.
