Fragment, by Warren Fahy

Pretty fantastic sciency thriller. A little Jurassic Park, a little Andromeda Strain, a whole lot of bloodshed, and some amazing imaginary beasties made this impossible to put down. Cricton-y science babble and vividly described scenes made it super easy to see this as a major summer movie- the beasties especially seemed like there must be CGI people just begging to design the spigers and disk-ants!
