Luke Von Batten, a spoiled, arrogant, young lord in Eighteenth Century England, beds every female that strikes his fancy. And there are many. One of these indiscreet affairs costs him his life and launches him into the monstrous world of the undead.
In the Twenty-first Century, Rebecca Richards, a molecular biologist, strives to unlock the mysteries of human cloning. When Luke volunteers to participate in her experiments, he prays she is the liberator hes been seeking, someone who can free him of the vampire curse.
After many failed attempts, Rebecca bypasses his contaminated blood and isolates the pure DNA needed to create a clone for him to inhabit.
Luke is ecstatic to be human again and Rebecca is flushed with the success of her life-long work. But she is harboring a dark secret. Her physician diagnosed her reoccurring neurological symptoms as an inoperable brain tumor. Having to deal with her own mortality, she makes a faithless decision to publish a research paper on her scientific achievements, something she promised him she would never do.
When he learns of her betrayal, he destroys all the documentation of her experiments, leaving the dying womans dreams for recognition and immortality in ruins.
In retaliation, she transfers her memory-bank into his discarded vampire body. Now wearing the guise of Luke Von Batten, vampire, Rebecca stalks her newly created clone. How will he pay for his treachery? With death or should she return him to the bowels of the hellish world he recently escaped?
You've got too much info here. Focus on the key points. Luke is a vampire (why that is so is just backstory). Rebecca is an idiot scientist who discovers the secrets of human cloning but has promised to never reveal it. Only when faced with her own death (cause yanno...changing her mind is so pedestrian) does she do the right thing and publish.
And just as a note: it's not the lack of documentation that would ruin her. Once the results are published, she's REVEALED how she did it. Then other scientists try to replicate the results (Allegra Goodman wrote a wonderful novel about this). Only if they can't replicate the results does she go down in flames.
You're missing the interesting part of the story here. Luke is ecstatic to be human again but Rebecca seeking revenge voluntarily becomes what he was ecstatic to give up. Now there's an interesting exploration.
You may have an interesting story here but it needs work.
