" Momma said that ghosts couldn't move over water. That's why Africans got trapped in the Americas.. They kept moving us over the water, stealing us away from our ghosts and ancestors, who cried salty rivers into the sand. That's where Momma was now, wailing at the water's edge, while her girls were pulled out of sight under white sails that cracked in the wind. "

― Laurie Halse Anderson , Chains (Seeds of America, #1)
