Nightingale Omega

For years vampires were peaceful creatures, only feeding on the willing. But that changed when the coven took over, pledging their race to the God of Debauchery and Murder. Now they are feared by the other races, driven by their lust for blood and sex.
The chimera princess and general, Hecate, is a strong warrior. She does her best to defend her people and protect the chimera Betas and Omegas, the breeding classes, who are often taken by Alpha vampires against their wills. But outnumbered on the battlefield after a long fight, Hecate has no choice but to yield to the vampires' demands-she must willingly go with the vampire prince, Vincent, and accept that she is his fated mate. If she does this, the other chimeras will be allowed to go free.
Alpha Vincent returns home with his fated Omega by his side, but Hecate is confused by what she finds there. Not all vampires are devoted to the God of Debauchery and Murder. Most Beta and Omega vampires are being neglected and abused. They want change but are too weak to fight for it, and those in power are much too strong. They seem to want out as much as she does but there's something else-something about Vincent. He seems to know her, as though they had met in a previous life. Hecate holds no such belief but as her and Vincent's lives intertwine, she'll need to question everything she thought she knew about life, love, and fate.
