I just finished Bios by Robert Charles Wilson.

Bios is an oddly short book, shorter than most novels released these days.  It tells the story of a world where all lifeforms have evolved to be hyper-aggressive, leading to death for any human exposed to even the smallest amount of material.

It's never drawn out why human's need to explore this world, but the follows a girl who was genetically altered to be able to resist the bacteria, etc. as a pilot program for others.

The short length, and lack of an important driver behind human needs to survive on this world, undermine the plot and make it less involving.
