Rebellious Teenagers

Jodi Picoult's The Pact is one worth considering and her Salem Falls even Nineteen Minutes (but some of you will have censored this one).
Of course The Gospel According to Larry / Janet Tashjian (which works for nearly everything actually and now has a sequel)

And Did Those Feet / Ted Dawe
Almost anything that Bernard Beckett has written
I Am Not Esther / Fleur Beale (and Further Back than Zero too)

Noughts and Crosses (and series) / Malorie Blackman
Stoner and Spaz / Ron Koertge (and the Brimstone Journals)

Uglies etc / Scott Westerfield

One Night / Margaret Wild

Just in Case / Meg Rosoff. David Case is a 15 year old who manages to save his baby brother from certain death just in the nick of time - but what if he hadn't? David is a natural worrier who suddenly realises that Fate is out to get him unless he reinvents himself by changing his name, his appearance and his character.

Box / Penelope Todd
