The Devils Teeth......by Susan Casey

This is one of the best books I've read in a long time. It is all about the Farallon Islands, which I knew absolutely nothing about. (only 30 miles from San Fransisco) The islands themselves are interesting enough, but the real wicked part is the fact that the waters surrounding the Fallarons has the highest concentration of white sharks on the planet.

I would definitely check this out if you are into books about the ocean, biology, and just plain ol' awesomeness!
