In the second book, it was just a bunch of pirate sailing stuff for kinda no reason that he is suddenly a master of even though he grew up homeless in a city with no access to boats/water. It meandered and didn't tell a very good story, at least not one I cared at all about.

The third book I can't even remember. I didn't finish it because I disliked the writing and story so much. That was close to 15 years ago, so I don't remember any details. If I remember correctly, at the time of the writing of that third book the author was going through a bitter divorce or his wife was dying of cancer or something extremely traumatic for him and his family, so the writing suffered. I do know that whatever the cause was, he opened up about his severe depression at the time.
