When Amelia turned 12, she began growing pearls. Every month, a crop of beautiful pearls bursts from the skin on her back. Her mother, Denise, believes her daughter is blessed, and sells the pearls to put food on the table. Amelia sees her condition as a curse. As the pearls form, her body aches and her skin grows feverish. The harvest of pearls brings temporary relief from the pain, but leaves her back marred by scars. Denise hides Amelia away from the world, worried that Amelia's gift will be discovered and she will be abducted for the wealth she can provide. Now a young woman, Amelia realizes she has become her mother's captive, and plans her escape. When she runs away from home, she finds a new family in a troupe of performers at a museum of human oddities. She soon discovers the world is much more dangerous than her mother feared.
