There was definitely a lot going on in The Shadows, and I think the one reason why I didn't go for five stars is that there were so many sub-stories and sub-plots that it took away from the two main characters - Trez and iAm - which was really too bad. Those two have been so mysterious in prior BDB books, and so I wanted to focus solely on them, you know?
The story is very solid, though, and the over-arching plot is still going very strong.
