I have mixed feelings. While I don't think it was the best book I've read from the series, I do think it had some redeeming qualities. 

It tended to drag on, particularly with the numerous shopping scenes. I couldn't help but think that the book could have been shorter if those scenes were cut out. 

The book did manage to make me continue disliking Nesta. To be fair, she's not coping well with the aftermath of the war which explains her behavior towards Cassian and others. On the other hand, Cassian deserves much better than what he gets in the book. I have hope that she might be able to turn things around in the next book and prove herself worthy of his love and attention.

I think it's still worth reading, but you wouldn't miss anything if you didn't.
