It is 1944 in England, and war has been closing in on the country for five long years. Ed is American, eighteen, and a waist-gunner on a B-24. Cassie is English, a talented young artist who lives nearby. When Cassie is commissioned to paint Boys on the Base it is not long before the two fall in love.


In the 1860s, Cassie wakes up in the American Midwest as a young woman with no recollection of her past. There she finds Ed, a man shadowed by guilt, and Amriel, a mysterious figure living by the river. Over time, Cassie will unfold Ed's guilt and the memories of their other lives.
