The magic behind John Greens books is that he can relate so well with teenage girls even though he is a middle aged nerdy male. All his books are so relatable that you don't want to put them down until there through. Making them short, but good reads.
The quality of writing in this book is the same as it is in it's companion. But if you are reading this book in search for answers to the cliff hangers made in Grimm Legacy don't bother. It is a complete new story line, and you barley get a glimpse of the old characters.
This is a really great book, it keeps you guessing about who the real princess is, and goes out with a bang, and a shock that you can kind of see coming if you are good at looking for all the foreshadowing clues.
A really good book that is constantly tugging on your heart strings. A book that is so well written you don't want to put it down until your finished. But when you finally do finish, you'll end up throwing the book across the room, because it doesn't really end.
I wouldn't suggest reading this book, unless you are really good at establishing characters. Each chapter jumps from character to character and never really establishes whose side of the story you are really seeing at that point in time.
