Answer:
In Chapter 7 of "Uglies" by Scott Westerfeld, Tally and Shay explore the city, looking for a way out. They stumble upon a group of people who are living together off the grid and are known as the Smokies. The Smokies embrace individuality and differences, going against the strict conformity of the city's extreme beauty standards. The girls are taken in by the group and learn about their way of life.
In Chapter 8, Tally's loyalty is tested when she is given the opportunity to betray the Smokies and return to the city as a pretty. In exchange, she is promised that Shay will receive the operation and become pretty as well. With her own desires for beauty pitted against her loyalty to the Smokies, Tally must decide where her loyalties lie and what she is willing to do to get what she wants. The chapter ends with Tally making a decision that will have a significant impact on her life and the lives of those around her.
