First, the narration: Travis Baldree does well. Into the 3rd book, nearly 20 hours of the story, and his voice is not tiring or annoying.
The story is good. Interesting, a wide and ever-expanding world, and does well not to trip itself up with mistakes.
The only issue and warning I think future reader/listeners should be aware: it is a slow-build story. Almost Tolkien-ish in that a long of description, growth, and small/subtle changes happen long before a major event happens.
