In my personal opinion I think that 'Beauty's Release' (the third and final book in the Sleeping Beauty Trilogy) was the weakest in the series. I expected to read more about Beauty but instead I felt that she was hardly mentioned in the third book, it was mainly focused on Laurent and Tristan. The story got a bit boring for me and predictable and I felt the ending was a bit rushed (needed less filler throughout and more effort for the ending). What made me like this book was the development of the Characters, I would say Beauty's change surprised me the most.
Overall, this book was OK, but a part of me is glad that this series is over.
