Dark and fascinating and brilliant from the very beginning. I fell in love with the story as soon as I read the trailer. The suspense is amazing, the reader is constantly wondering who of the three has the best chances, who will flee and whose guardians will manipulate and make the best of it. The side characters are as well developed as the main ones. A few love aspects are intertwined and make the story spicier and more dramatic. The story is twisting and turning enough so that one can't really tell what to expect next. Getting to know each Queen and 'watching' the story from their perspective is a thrilling experience.
And– spoiler alert, believe it or not, in the end all three sisters are still alive, more or less. The sequel is already ordered.
