The Selection
The Selection series, which is what Cass is best known for, is a series of five young adult novels set in the fictional country of Illéa, formerly the United States of America. The books are about a competition known as The Selection, where citizens of Illéa compete for the current king's heir in marriage. The first three books are from the point of view of America Singer, joining the selection after bribery from her mother, who doesn't know she is in love with Aspen, who is a caste lower than her. The two sequels, The Heir and The Crown are written from the point of view of Princess Eadlyn, the firstborn daughter of Prince Maxon and Lady America Singer.
