I finished Pretties this weekend. Enjoyed it too, but not as much as Uglies. Decision on the series was not to include it in my 4 - 6 grade collection.Some higher level 6th graders would enjoy it, but I didn't think spending almost $60.00 on the 4 books would be a wise use of my budget. Also when my elementary guidance counselors were in the office and I ran that "hangover and drunk" by them that I had found in the 2nd book, they immediately said "Don't think so."
Interesting note, however, about the flash tatoos in Pretties----go to the following link

Reminds me of the Pretties.
