Ryan and Ben were intrigued when Mr. Kramer, their middle school science teacher, told them that time travel was possible. That evening they stood in front of a 150 year-old mirror, and their lives were forever changed. Can two boys from the 21st century survive in the turbulent years just before the civil war? Can the mirror that took them back in time return them to the present? And after meeting the freckle faced, red-headed and fun Laura, will Ryan want to come home again?
