However, I passed it to my nearly teenage son, who very much enjoyed it.
After he finished it, I took it back and Homeland - the sequel to Little Brother was on the new fiction cart. My son enjoyed that too.
However, I called it a 'juvie' because the book fits the older style better: A young person Gets Into Trouble and uses Native Wit, Loyal Friends, and a few Helpful Adults to Solve The Problem. It not incidentally teaches Moral Lessons by example, like how important it is to stand up for yourself and so on. Modern YA stuff is more psychologically deep and less focused on Solving The Problem.
Anyway, the target audience is middle school to high school. The protagonist is in high school, but it's a rule in kid lit that kids will gladly read things meant for older kids but never stuff meant for younger kids.
