Highly recommended.
My thanks to the nice people at Orchard for sending the book. We also have a review of [[The Trouble With Donovan Croft by Bernard Ashley]].
Those interested in exploring gang culture through fiction will also enjoy [[The Dirty South by Alex Wheatle]]. It's marketed as adult fiction, but it suits that crossover age. If they're ambitious enough, they could also look at [[Gang Leader For A Day by Sudhir Venkatesh]], an interactionist study of real gangs. [[The Knife That Killed Me by Anthony McGowan]] is a properly teen book that gets inside the head of a boy that's going wrong, while [[Teacher's Dead by Benjamin Zephaniah]] has Jackson Jones trying to find out what really happened, just as Ashley's Amber does.
