Although I though the original series was decent enough, I really didn't care for this tie-in. The relationship between Shay and David just irritated me. The explanation of David's scar was stupidly melodramatic. Zane seemed out of character a lot, and I disliked that Shay was depicted to have once been as invested in becoming Pretty as Tally was. I thought it undermined her. Also, people tell Shay things that she doesn't seem to remember at appropriate times in Uglies-the-novel. Sometimes adding more to the story makes it less.
