I just can't believe this could possibly be the end! Well, it definitely went out with a bang! So, this book was mostly about Thais and Clio's battle within themselves (Will they truly become as evil as Melita?). Also it was totally about relationships, which is the part I've always loved the most, who does Clio want to be with, really? what about Thais, will she find her match? and even the other members of the Treize besides Richard and Luc, are mixed up in some relationship drama! and then you have the underlying thoughts of what could be next! i mean they already performed the Rite what could they possibly do to top that? well you'll see! This book had so many twist and turns! Thankfully some outstanding questions that were left on everyone's mind from the last three books were answered although out the book. But the ending unfortunately left me with more questions that could probably be answered in another book if only Cate would make one! maybe she could make a super edition like in the sweep series. that would be great! but i guess its up to you to decide that for yourself! go get this book, it will make you laugh, it will make you cry, it will make you talk to yourself! And it will make you happy that you own such a great book!
