The Chance of a Lifetime — Grace Livingston Hill

Sherrill and Alan, lifetime friends, have always known they belonged together. But when Sherrill is invited to New York to visit her wealthy relatives and Alan is offered a chance to travel to Egypt and take part in an important archaeological dig, the offers seem like the chance of a lifetime. -- But there is more to these offers than meets the eye. Sherrill's aunt has her own plans for her niece, plans that would horrify Sherrill if she knew; Alan must decide if he will sacrifice his family for his career.

Are these the real "chances of a lifetime" they appear to be? Or will Sherrill and Alan miss their chance to learn what true happiness is?
