Black [AF] America's Sweetheart #1

Only black people have superpowers. This includes Eli, who is adopted by a white family and whose father works for the government. When Eli develops powers, he puts her into training and sends her on approved missions. She loves helping people, but Zion, who attacks the government center, insists that she and Eli are sisters; their parents sent them into the past from a time in which superpowered blacks are slaves of the white government. Zion beats Eli into a coma, and then collapses into the ocean. Eli's mother demands more protection in the hospital; a rogue youth appears by Eli's bed.
