I did think that any pirate novel nowadays was going to be overly influenced by "Pirate of the Caribbean"; but "The Pirate Devlin" surprised me. For a start, it is largely believable, in that all the events and action could easily have taken place. There isn't more killing than is historically likely, and the hero is by no means superhuman.
My only concern with it was that the language in which the book is written is ever so slightly archaic, which makes it a bit difficult at times - one has to read it carefully and intelligently! This didn't take away my enjoyment, but it did make it a little hard to get into in the first place - I actually started it twice before I could get beyond the first few pages. But I quickly got used to it, and it wasn't a problem from then on.
Yes, a good book - not a masterpiece, but well worth reading if you like the pirate genre.
