This book was a fantastic addition, truly. Here we have the retelling of Rapunzel when we meet Cress who is a computer programmer/hacker that has been placed in an orbiting satellite by Queen Levana to spy on earth. Basically she revolts and joins forces with the other four. We start the novel when the four go to rescue her but it all goes wrong, as things tend to do. This begins a series of "splitting up" that continues until the very end of the series. The team is split in 3 - Cress and Thorne end up in the Saraha, Scarlet is kidnapped by Lunars and in an act of sheer brilliance Cinder barely escapes with a badly wounded Wolf and the Queen's pilot who will be our next main character, Jacin. This book has them all trying to both stop the wedding of Kai and Levana and trying to find one another once more. It ends in near perfection when we're finally introduced to our final fairytale - Winter.
