Another Napoleonic historical series -- this time following the exploits of naval captain Jack Aubrey and surgeon Stephen Maturin. The level of (implied) realism is impressive. O'Brian clearly knows his stuff, and his battles are based on historical encounters; there's also a large cast of interesting characters both on- and offshore. I could argue that the ending felt a bit contrived, but I thoroughly enjoyed it regardless, and I'll look forward to reading more of the series.
