I loved the first book in the Uglies trilogy, but the last 2 were mediocre at best. Hoverboard adventures don't work anymore. "Pretty" talk is old already. And I didn't care for the glamorized self-cutting that helped the Pretties think more clearly. The only new things here are Pretties turning into Specials and the sneak suits that change colors and textures based on your surroundings.
There were also very few pages where storyline was interesting enough to slow down and read rather than skim boring conversation and contrived action sequences.
I disliked Shay as much as ever, but suddenly Tally was just as despicable. I had a hard time believing Tally was even the same lucid character as before. All the likable characters from past 2 books had been boiled down to characters with very little personality. When one of them died, I didn't even care.
I can't see myself wasting money on the 4th book in the series.
