My biggest unanswered questions are:
*Who spiked the orb (my guess would be Ro)
*Why are Barrons and his men the way they are (beasts)?
Now, I have new questions - to be answered in future books (I hope) lol:
*How will Mac repay her debt to UK/DEG as well as the Grey woman?
*I don't understand how QA has been in human form for so long (spell) that she naturally has human expressions, yet according to V'lane/Cruce, she was in the Unseelie Prison (or missing, he said) for years? Unless I'm messing up the timeline between Spell and the Fever series...
And then obviously, questions abound regarding Dani, Christian, where they all go from here... :)
