While I was quite intrigued with Pantomime I couldn't get into Shadowplay.
The outline of the two books is very similar, and that makes the turns rather predictable, if not the actual events. Running, hiding, working enthusiastically/feverishly, revelations ho!, work work work and build up to an awesome show of all that we've learned that, at least this time, we didn't miss much of. Before we has a pantomime, this time it's a magic show.
The entire book felt more rushed and less finished than the first instalment. The world building is still awesome mind you.
But I wasn't really impressed with the storyline nor did I feel much was done with the character building.
I was left rather disappointed. And I still got questions, but frankly, I don't think I will read the next installment.
