Isla Morley discusses her novel Above. It’s about a teenager who’s abducted by a survivalist and locked away in an abandoned missile silo in Eudora, Kansas. At first, she focuses frantically on finding a way out, until the harrowing truth of her new existence settles in—the crushing loneliness, the terrifying madness of a captor who believes he is saving her from the end of the world, and the persistent temptation to give up.
