Holy smokes, I can't quit studying this cover! It is exquisite and so eye-catching! First of all, if Marie Lu is singing the praises of a book, then my students are going to LOVE it. This much I know. Second of all, this book is what YA book dreams are made of -- complete with the map at the front (my favorite bookish addition)! I am never much into a book where there is a lot of world-building, but this one might just be an exception.
