The Selection by Kiera Cass

America Singer lives in a time of Caste systems.  She is a Five, so she can work for a living as a musician to bring food to the family.  Nevertheless, there is never enough.  Her boyfriend, Aspen, is a Six, so he is a servant to all others.  She knows that they can never have the permission of her family to be together, and if they choose to be together, America will be a Six the rest of her life.  She is, however, in love and willing to do what she needs to do with stay with Aspen.

Then the Selection happens....women all over the country are asked to come to the office, turn in paperwork, and have their picture taken so the Prince and his family can choose his bride.  He will choose 35 women as part of the selection, and one of those women will rule with him as queen.

America never dreams that she will be chosen, but she is, and she and 34 other women are flown to the capital to compete in the Selection contest.  Aspen tells America to go through the process because she is compensated handsomely for her time, and her family desperately needs the money.  She leaves for the contest feeling betrayed and angry.

It never occurs to America that she might actually like Maxon, the crown prince.  America also finds out there is much, much more to being royalty than she ever expected.  This is book #1 in the Selection series.  Bachelorettes, get ready to compete for your prince!
