I loved this book, I loved this series & I'm hoping eventually there's more books in the world of the Moroi & dhampires. I really loved how the Ruby Circle tied certain plot stories up & how the relationship between Adrian & Sydney unfolded. Between Bloodlines & this book, Sydney really matured & came into her own. From how she stood up to her dad & the Alchemists just showed her growth. In my opinion there was 1 major, significant & kinda mind blowing revelation (between Dmitri & Adrian) that occurred that was left hanging. I would have liked to have seen more on that & how they worked it out & how it affected them.Other than that though, I really loved this book.
