The sign of the carved cross

"Katie joins her friends in being mean to the new girl, Lily. But suddenly, Katie becomes the new girl-in 1675! She has no idea how she traveled in time to a Native American village, but she's hoping the young woman she meets will be nicer to her than Katie was to Lily. Tekakwitha is a quiet girl with scars on her face from a terrible disease. Tekakwitha's family doesn't accept her because of her faith, and soon she and Katie have to runaway in the middle of the night. Will Katie ever find her way back home?"--Back cover.
