You are probably one of the very few who've liked Tower Lord better than Blood Song. I felt exactly the opposite - in my opinion the second book changed too much of what was awesome in the first one, like the story-within-a-story element, Vaelin being the center of the narrative, cohesive plot, etc. For me the next two books were too much world-building and trekking, the story went all over the place and very little of it made sense in the boundaries set by the first book and I just don't like when a series veers too much of what it promises to be in its first book - that's one of the main reasons I don't rate The Demon Cycle by Peter V. Brett too highly, he started of with cool medieval setting and conflict, and then the consecutive books just segwayed into arabic themed soap opera. Same here - strong, concise start, investment into the main protagonist, and then a barrage of side-characters turned main characters with mostly meh story lines. It's my personal opinion though, I can understand how someone could not agree with it. But as I am now reading The Red Knight series, from which I've finished the 2nd and started on the 3rd book - it's exactly the opposite approach. The author introduces a galore of characters and forces you to deal with it, and eventually you learn to trust him with this kind of story-telling, and to even like it, where Anthony Ryan started in one style and finished in a completely different one, not delivering very well on his initial tone and premise when it came to the sequels.
