Newly-bitten tattoo artist Riley Poe feels herself changing in unimaginable ways. Eli Dupre, her vampire lover, has seen the change in her and fears for her humanity. His rival, Victorian, tells her she must see the patriarch of the vampire cult that attacked her to save her soul.

In the vampire cult's fortress in Romania, Riley will face her worst fears—and the dark powers threatening to destroy her. And she'll have to do the one thing she's been determined not to do—put her trust in Eli.
