Summary from book-jacket:

When they first met, George was a nice man in his thirties,
who loved his wife and children.
Doris was a nice lady in her twenties,
who adored her Harry and their kids.

It happened in 1951, in a romantic country inn.
Doris was an adorable young housewife on her way to a religious retreat.
George was a hot-blooded C.P.A. on his way to a set of books.

First they fell in bed - then they fell in love.
Then their risqué rendezvous ripened into a full-blown affair.
Not the kind that breaks up marriages and hurts people, though.
Instead George and Doris find themselves repeating their tryst annually,
resisting in the interim the urge to call one another on the phone.

And so the years go by ...
Doris changes from dumpy to svelte, from uneducated to hip,
from housewife to women's libber to businesswoman.
George climbs the financial heights, moving into bigger houses
and making more babies with wife, Helen.
There are times when they hardly know each other,
times when they're closer than ever.

Through 26 years, two wars, six kids, seven Presidents, lowering morals,
raising consciousnesses, and shifting values,
they laugh, cry, lust and love - for one fantastic weekend a year!

Based on the long-running Broadway play and hit movie starring
Allen Alda and Ellen Burstyn, Same Time Next Year is a charming,
sentimental, funny and, most of all, universally appealing novel.
