For those of you who have read uglies, pretties and specials by scott westerfeld???

i read uglies amd loved tally as a character but i hated her in pretties. even at the end she was a total jerk to david. is specials does she make things up and stuff??? does she get the personality she used to have by the end? dont worry about spoiling it- i just wanna know if i'll like it cuz i was soooo disappointed in pretties.
