I have recently finished the third book of the selection series and it was great. I was cautious to start the first book of the seris because it looks like more of a "princess" book if you will, but I am so happy that I took the offer to read it. If you do not already know what it is about here is a short summary (ps no spoilers:):
It about a girl named America Singer who lives in a world where there are these things called castes. This castes ditermine how much money you have and your rank in society. America is a 5 caste, that is pretty low. But, the Prince that is a 1, has a thing called a slection, that takes a group of girls from random castes and puts them in a competition to become his bride and the next queen. America gets picked, to her demise and has to go in the selection even though she loves Aspen a boy from her caste. She is torn between them and doesnt know who she'll pick.
Sorry if this is sloppy, its my first review :)
