From www.commonsensemedia.org here are a couple of suggestions on what to read after The Hunger Games:

“Here are some top picks for more dystopian novels — books that imagine a not-so-rosy future under a menacing and oppressive regime, in which teens and others must rely on their wits, courage, and strong friendships to survive:

• Divergent by Veronica Roth – Exciting, violent dystopian thriller is original, addictive.
• Matched by Ally Condie – Fun, provoking start to dystopian series for teens. A PRC book too.
• Trash by Andy Mulligan – Powerful adventure about dumpsite kids a true treasure. Also a book on the PRC list.
• Incarceron by Catherine Fisher – Dystopian bestseller is full of plot twists, complex themes.
• Brave New World by Aldous Huxley – Satire of ultimate consumerist society still packs punch.”
