SPOILER: ugh. I’m barely into this book and already Thea is mentioned as the possible culprit. I was bored of Thea as the recurring Terminator style villain several books ago. Why do authors think this Terminator “they always come back” concept is interesting?! I had hoped she died previously when she fell off the tower. Nope. I had hoped she died in the last book when she was skewered by shadow spikes. Apparently maybe not but man i hope so. I like these characters and tbe world the author has created but Thea is a boring villain and this whole the villain is never killed and always comes back a la Jason in the horror movies is BORING. EDIT: fortunately despite references to her, she didn't return. One can only hope this remains the case and she doesn't get trotted out for a "surprise" return in the final installment.
