Still mourning the loss of her beloved grandmother and shaken by her mysterious, dying request to "find the baby," Abbi has just arrived at UW Madison for her freshman year. But on her second day, she wakes up to a different world: 1983. That is just the first stop on Abbi's journey backward through time. Will is a charming college freshman from 1927 who travels forward through time. When Abbi and Will meet in the middle, love adds another complication to their lives. Communicating across time through a buried time capsule, they try to decode the mystery of their travel, find the lost baby, and plead with their champion, a kindly physics professor, to help them find each other again ... even though the professor gets younger each time Abbi meets him.
