Trapped in between are the Native Americans, ex-slaves, and European refugees, led by Benjamin Franklin and the Choctaw shaman Red Shoes. But the balance of power rests with the French woman Adrienne de Montchevreuil, whose grasp of science is the equal of Franklin’s, whose magic may be stronger than the Choctaw, and whose shocking secret may call into question where her true allegiances lie . . .
