If you are looking for a great paperback to give to someone that enjoys reading or simply looking for a book to read during the holidays, I highly reccommend The Footprints of God by Greg Iles. Although there is some religion involved, this is not a religious book, simply a fast-paced novel. From Amazon:
"My name is David Tennant, M.D. I'm professor of ethics at the University of Virginia Medical School, and if you're watching this tape, I'm dead." Tennant works for Project Trinity, a secret government organization attempting to build a quantum-level supercomputer. Using advanced magnetic resonance imaging techniques, Tennant and five other top scientists have supplied Trinity, the experimental computer, with molecular copies of themselves as models for a neurological operating system. As Trinity comes to life, the men who control the experiment begin to split into competing factions, each determined to use the computer for his own ends. When Tennant tries to shut the project down because of ethical considerations, he is marked for death by the beautiful but physically and psychologically scarred Geli Bauer, head of security.
If you are a fan of Dan Brown, you will like this book.
