Return to Harmony by Janette Oke and T. Davis Bunn

Jodie and Bethan had little in common until a homeless dog brought them together. But from that day on, the two became inseparable. As different as night and day, their friendship thrives through shared trials, joys and finally devastating loss.

Then the day comes when it seems that faith itself drives a tragic wedge between them, seeming to finalize when Jodie goes off to college. Now, with the United States joining the war effort in Europe, Bethan wonders if there will ever again be a return to harmony . . .
