What's next?

I've recently been advised to start reading the Aubrey-Maturin series by Patrick O'Brian.The first book of the series is the now-famous story thanks to Russell Crowe, 'Master and Commander'. The series, I've been told, is much better than the movie, following the friendship and adventures of a ship captain and the doctor traveling with him. If the draw of a compelling story is not enough, the series has been touted for its historical and medical accuracy. Who knows, if one isn't careful, one just may learn something!
