The premise of the book, finding a cure for aging is very interesting. The book starts out a little slow, but after the kidnapping of Zoe Kincaid, the ageless adult/teenager, the storyline picks up. A quick read that will keep guessing until the end.

n a Washington, D.C. research lab, a brilliant scientist is attacked by his own test subjects. At Columbia University, a talented biochemist is lured out of her apartment and never seen again. In the Justice Department's new Bioethics Committee, agent Les Mahler sees a sinister pattern emerging. . .

Zoe Kincaid is a petite college student whose rare genetic makeup may hold the key to a powerful medical breakthrough. When she is kidnapped, the very thing mankind has wanted since the dawn of time threatens to unleash our final destruction.
this was an interesting concept. I did find the characters annoying and not realistic...Zoe and Natalie both seem to lack common sense, no matter whether you want to argue that zoe is 14 or 20. But the storyline raises excellent ethical questions and a good read.
