Polls close Sunday at 1 p.m. ET.The HobbitTo Kill a MockingbirdThe landmark fantasy novel that launched a million quests, dragons and dwarves optional. Not as bleak as grown-up successor-epic Lord of the Rings, the tale of Bilbo Baggins thrills and chill kids of all ages. — Darren FranichA shortlist of great American novels would be incomplete without Lee’s Pulitzer Prize-winning coming-of-age tale, which revolves around scrappy tomboy Scout Finch. The novel’s setpiece is a racially-charged trial that Scout is almost too young to understand — though her retrospective recollections of it are anything but childish. — Hillary BusisThe Princess BrideThe Harry Potter seriesHello.

The four-book series begins with Tally eager for her sweet sixteen, as it’s the age at which all citizens endure extreme plastic surgery to become part of the ‘Pretty’ class. — Jennifer ArellanoThe Hunger Games seriesThe Fault in Our StarsThere’s a reason that Collins’ dystopian tale inspired a seemingly infinite army of post-apocalyptic imitators: It’s just that good. Brave, poverty-hardened Katniss Everdeen becomes an unlikely revolutionary when she volunteers to compete in the 74th Annual Hunger Games; the rest is blockbuster franchise history. — Hillary BusisIn this heartbreaker, teens Hazel Grace Lancaster and Augustus Waters meet in a cancer support group and fall in love.
