An immortal vampire makes a mortal man an offer he can refuse.

I blinked, digesting the offer Nessa had just made. She was playing to my fascination with eternal life. I turned and walked to the living room window, watching the city below, thinking about living through the centuries and experiencing future times I wouldn’t naturally know. Closing my eyes, I imagined a world in which we would always be together. But a dark vision crossed my mind, knowing I would never see the light of day again. I couldn’t give up my humanity to become a vampire. I walked back to Nessa and took her hands in mine.

Nessa watched me, looking for clues to the emotions I hadn’t expressed. “Our feelings for each other are real, but I understand what you are telling me. Do what you must.” Her mouth closed, and her eyes turned downward.
I left her apartment and was walking beside Central Park within ten minutes. If I took too long to decide, our relationship would end. Nessa’s loneliness had spanned more time than I could comprehend. She’d chosen me, perhaps impulsively, but now I knew how much I meant to her.
