Princess of Seduction (Dracula’s Bloodline #6)

There's a fine line between hate and love.

The seductress vampire Irina turned young scholar Lazarus into a vampire many years ago. He hates her for it, but now they're forced to work together on a mission to discover the secret to human immortality. Yet as Lazarus goes discovering Irina's terrible past and what turned her into a princess of seduction centuries ago, the line between hate and love blurs dangerously. Can Lazarus save Irina's doomed soul, or will he go down with it?
