Grace Livingston Hill 
Prodigal Girl 

Teenager Betty Thornton is devastated when she learns that her father will be uprooting his family and moving to a remote Vermont farm far away from her social circle of friends. Rather than passively accepting, Betty takes matters into her own hands and makes plans to elope with Dudley Weston, the reckless young boyfriend she left behind. When her dreams of a breathtaking, whirlwind wedding turn into a disastrous situation, will a handsome stranger be able to restore Bettys faith and lead the prodigal girl back home? Or will one hasty decision cost more than she bargained?
