My first thought when I read the premise: An entire book of Ash and Puck? Sign me up! 
 Then Ariella came into picture and I can't say I was too happy about that, firstly because I didn't trust her intentions until the very end of the book. I am glad that her return meant the whole animosity between my babies could be stopped at last, the damned promise no longer made sense if she was alive and that was a relief. 
 I missed Meghan's presence throughout the book, but I realized this was a book about Ash's journey and of him coming to terms with his wish to become mortal to uphold his promise to Meghan. It was a fantastic journey, Grimalkin is one of the best characters in the books, and he didn't disappoint me in this last installment. The animosity between Grim and the Wolf reminded me of Puck and Ash so much. 
 After reading the book I wish I could read one from Puck's point of view because he's definitely the most interesting character in the books for me. 
 This was without a doubt my favorite book so far. I'll get to Ethan's books soon.
