19 Books You Wish There Were Sequels To

Why We Love It: Five-year-old Jack has spent his entire life trapped with his mother in a predator's lair, until she plans their escape—and his world is upended. What could have been a cheesy, ripped-from-the-headlines drama became a singular literary achievement because of the brilliant way Donoghue told it, through Jack's voice.

The Sequel: How does a child raised in almost unimaginably harrowing circumstances grow up? Whom does he love? And how? Call it, simply, Jack.
