A difference between these first and second books is also in the point of view. Post Captain is told mostly from Stephen Maturin's POV, while Master and Commander had a big mix of Jack and Stephen. There are also several gaps in the story that almost made me think i had put in the wrong disc. At one point we see Stephen about to go on a mission and the next track it is several months later and he is back in England. I didn't particularly like the jumps.
I did like the new characters and coming back to some from the first book. I liked the women, Sophia Williams and Diana Villers, with whom Jack and Stephen become involved. I liked the life on land sequence early in the book; it reminded me strongly of Jane Austen. I also enjoyed the comic, if unbelievable, scenes of Stephen and Jack fleeing France with Jack dressed in a bear suit.
lastly, as occasionally happens with library audio books, there were a lot of scratches on some of the discs which made them skip and stutter. And of course a few of the bad ones were in important places. Like when Jack finds out his agent has run off with his prize money, which he now owes back to England. I missed the track that explained this and didn't catch on to what happened for a while. I am sure that didn't help my enjoyment.
Overall, a 5. i picked up books 3 (HMS Surprise) and 4 (The Mauritius Command) to listen to on the trip to Louisiana. I'm headed home for Christmas!
