Solved: Group of people kept hostage in mansion discover baby harvesting operation [s]

[Stephanie]

This is killing me! I read this book several years ago and have since forgotten the title, as well as most of the plotline. What I do remember is that somehow, a group of people are brought and are invited to stay at this mansion b/c they are unknowingly to be a part of a secret quest to find a "fountain of youth" serum made from manufacturing babies, etc. Really sick and twisted but a wonderfully crazy read.

I read this too, I think. It might be one of those medical thrillers by Michael Palmer, Robin Cook, or others. I'm looking...
