It seems so. There haven't been any new releases for a while, suggesting that they've been discontinued. Maybe it was due to various reasons like low sales or changes in the publisher's strategy.
Well, the 'Uglies' novel is set in a world where there are strict divisions based on appearance. Uglies are those who haven't had the surgery yet. The story is about a young girl's journey. She uncovers a lot of things about the society's idea of beauty and how it controls people. For example, she finds out that the so - called 'Pretty' people are not as free as they seem and that there are many problems with the system that forces everyone to conform to a single standard of beauty.
