Have you read any Michael Talbott? He was a scientist, but most people don't know he also wrote a vampire novel
I have not - Im loking online and it seems that the Delicate Dependency is hard to find online.  Can you tell me more about the story line?
It's a period piece, about a man who is caught up in vampire intrigue while searching for his missing daughter. It's very intelligently told. 
When you say period piece, in what time and place is the novel set?  Is this reminiscent of Anne Rice's novels?
It takes place in the mid 19th century. Do you like Ann Rice? 
I read her novels many years ago and loved them.  I msut admit I have not read any other vampires fiction lately.  I did recently watch Penny Dreadful, however, and loved it.  I love 19th century gothic and horror stories.
I think you'd like the Talbott book, then. It was out of print for a long time, but  i've seen it's back in print now, even with a kindle version. 
I will try and get a copy.  Did Talbot also write Your Past Lives a Reincarnation Handbook? Is that fiction or nonfiction??
He wrote the Holographic Universe, it was pretty well known several decades ago. Not sure about any reincarnation books. 
Is this fiction and what is the plot or premise? - that he whole universe is just a hologram?? Would you also recommend this title?
No, that one is non-fiction. I remember it being pretty good, though it is likely pretty dated by now. 
I see he wrote a few other novels before he passed away including Night Things.  Have you read that title or would you recommend any other vampire fiction?
