The Runaways — Patricia Robins

When Judith and Rocky elope to Gretna Green they sincerely believe marriage will solve all their problems. But the elopement proves to be the beginning of an entirely new set of difficulties... Rocky begins to wonder if his parents were right - is he even in love? Were they too young after all? And in the background Gavin, Judith's boss, watches her disillusionment with a concern which is growing into something more.
Their love was a wild impulsive thing... until that moment of heartache.
