Lovership of the Stake — J. Morgan

Joan Ravell thought she'd pretty much had her life figured out until a hit squad shows up, interrupting that carefully laid out delusion. Next thing she knows, she finds herself drawn into the first Vampire war in three thousand years.
That would be so bad, but her dead lover turns up unabashedly alive, truly blowing her world apart.
Fighting emotions she'd locked away ages ago, Joan must team with the one time love of her life to unravel the ancient secret that now threatens not only the Vampire race but the entire world.
Can the world survive a tension that's been building for over three thousand years?
Oh, and then there's the Vampire planning to bring back the ultimate evil.
Just another small problem to deal with when you're the original Queen of the Damned.
