you want to give a synopsis? 
Sure... The story is set in the San Francisco Bay Area, where the biotech revolution was born. A middle aged couple work for a big biotech company called Genetechna. The woman, Jasmine Metcalf, is a bioinformatician and protein modeler. Her husband is an MD. Together they develop a treatment for a child dying of progeria, but because of the right wing political climate at the time of the story, they are forced to treat him in secret because the treatment involves stem cells and gene modification. Soon they realize that it could be used to treat normally aged people as well. The get hooked up with a "Garage Biotech" community that flies completely under the radar, and begin to treat several people. I found the Garage Biotech aspect, with labs set up in trailers in the desert and a shipping container in Santa Cruz to be particularly appealing. I don't want to spoil the story, so I wont say too much, but rich and politically powerful players become involved, and there is much intrigue. Also sex [:o], and violence (needless to say...) I found it gripping and fun. I had a hard time putting it down. (Stayed up wayyy too late one night reading it.)
If the book becomes popular, it would help to put the immortalist meme out in the popular culture. It presents life extension as a good thing, while the bad stuff that happens is laid at the hands of the power mad and religious extremists. The technology that they use is all at least plausible. Much of it exists already (like Craig Venter's artificial chromosome) and the rest is at least being explored. In their world, somatic cell nuclear transfer and very reliable gene delivery methods exist and work well. I'm pretty sure that we will see this in our world before too terribly long. On the book's website, they made the point that it was not "science fiction", but was more near term than that. I think that's a reasonable assessment. I think it would make a great movie.
