I really loved "Uglies", "Pretties", & "Specials". I find myself resisting "Extras" because the characters aren't the same ~ I grew so attached to Tally, Shay (most of the time!), Zane, David, etc. that I can't imagine how this one is considered part of the same series.
It wasn't hard to get into at all. The new characters are just as interesting and lovable, and the plot is thrilling. It's not really part of the series, since the series was a trilogy; it is more of an "extra" book. However, it ties the trilogy together in the end. Definitely read it!
Any feedback would be SO greatly appreciated!
