Each morning as parents drop their children off in the Butterfly Garden room at the Penn State Child Care Center at Hort Woods, 2012 human development and family studies alumna Grace Hakizimana is there to greet them. The preschool teacher smiles at the babies and toddlers as they come through the door. She speaks to them softly. She helps them settle into their favorite activities. She treats them as if they are her own. On the outside, Grace radiates warmth. But on the inside, there is darkness.

When Grace was just 16 years old, her life in her home country of Rwanda was turned upside down. All around her people were murdered in a genocide that would last 100 days and leave 800,000 people dead.
