Part of me expected that Urik would not cause trouble before they get to lay Tresten to rest, considering it was Tresten who had shown some degree of hope for his redemption. Endric, after learning more from him and his background in the previous book, is now a bit more lenient to him, which now surprises Senda. Strange how one who wanted to have him dead now acts as the one to keep him alive.
To keep this spoiler-free, I can only say that there will be more twists as things start happening.

When I started reading this series, I believed it would be three or four books. Maybe it was hinted somewhere. Now, after fifth, I still feel it's not the end. I hope it's not the end.
And I'd really want to know more about Urik's background. There's a hint of tragedy that sent him on his downward spiral, but nothing much about it was revealed.
