Two Recommended Books

Rainbow's End, by Vernor Vinge
Vinge is best known as a proponent of the idea that humanity is approaching a Singularity where our scientific progress creates a self-evolving machine intelligence which enables a feedback loop of technological expansion.
His other novels are set the in far future, while this one is set perhaps twenty years from now. Vinge is super at extrapolating current technological trends in plausible ways, while also giving us engaging characters and action. The world he describes lets everyone construct their own virtual reality and superimpose it on the real one. It is also a world in which medical science has made amazing discoveries, but some diseases remain uncured creating a roulette of medical cures depending on your condition.
The main character is a poet who is cured of Alzheimer's among other physical ailments and finds himself with a restored body in this new world. He becomes caught up in an international plot that would kill most of humanity.
I highly recommend this book.

Quantico, by Greg Bear
This is the latest novel by my favorite hard science fiction author. Quantico is set in the very near future, and as the name suggests it revolves around the FBI. I would call this a horror story about what is possible for terrorist groups with the acceleration of genetics in the past ten years. A young FBI agent, his partner, and his father investigating the possible use of anthrax end up discovering a far more frightening possibility for modern criminals.
As with Bear's other books, his characters are smart and well-defined. If you are familiar with his other work this is a good book, but if you have not read Greg Bear, I would start with Eon, The Forge of God, or Darwin's Radio.
