Wow. Wow. Wow. 
 So I have literally just finished this book and I cannot put into words how I feel about it. This book was incredible. Everything fit together so effortlessly (AND THAT EPILOGUE OMG). 
 I do not know how i will wait for the next one. Or how I can read another book after that. 
 This was incredible. I don't think I can say that enough. 
 Yes, when starting this book I was a little annoyed. Where was Twylla? Lief? What about all those characters we had met in the last book? I was also really skeptical about Erinn. But this book was written so well, and all the characters from the last book feature into this one really well. 
 It was all so clever and I'm really happy that I read the epilogue of The Sin Eater's Daughter before starting this one because it is important in The Sleeping Prince. Everything melded together flawlessly in Part 2 of this book. Even unanswered questions from The Sin Eaters Daughter. 
 I really recommend this!! 
 Do not know how I will wait for the next one. And also, to readers who may be struggling continuing with this one, the first part is a little slow and boring, but then it gets AMAZING. Read it, you will love it! 
 I really hope the next book we will have both Twylla and Erinn's POV!!! 
 UPDATE 
 Just seen the cover and title for the third book The Scarecrow Queen! Cannot wait for a blurb:D :D :D And the cover is as pretty as the others, yay!
