I just finished a couple of pretty interesting books...

The Devil's Teeth: A True Story of Obsession and Survival Among America's Great White Sharks

The Devil's Teeth is all about a journalist who gets involved with the biologists studying great white sharks in the Farallones, islands about 20 miles due West of San Francisco.  It's an interesting portrait, not only of the harsh reality of life for a shark, but of the harsh reality of the people who live to study them.  Not an easy job.  Unfortunately, the author's obsession with the sharks leads to her violation of the rules of the study, which ultimately result in the lead biologist losing his job.  I notice that part gets downplayed significantly.  Other than that, it's a very well written account.

Adrift: Seventy-six Days Lost at Sea

 Adrift is about the truly remarkable adventure of Steven Callahan, who survived in an inflatable life raft for 76 days in the North Atlantic.  Only one other man is recorded as having survived at see that long solo.  Callahan's sailboat was sunk (he thinks by running into a whale) while only a few days out from the Canary Islands, headed for the Caribbean.  Using only the tools in his raft and survival kit, he manages to provide himself with enough food and water to make it all the way to Guadeloupe, where he was rescued by some fishermen.  Callahan showed some pretty amazing competence and ingenuity, which makes this a very interesting read.
