Gaby and Connor seem to have a loving marriage - one that is built on knowing every last intricate detail about one another, or so Gaby has always believed. When their son Ethan sets off for university, discovering for the first time, the raw and uncontrollable intensity of falling in love, Gaby and Connor will be alone again - a chance to rediscover their relationship, just the two of them.

But there is one person missing from Gaby's life. One person who she cannot forgot - Nancy, her best friend since childhood. As teenagers they shared their deepest secrets, fears and dreams for the future. As adults they discovered love - Gaby with Connor and Nancy with Gaby's adored brother, Stefan. The foursome became inseparable.

Then one day, Nancy upped and left.

Now, almost twenty years later, with Ethan away from home, Gaby finds herself idly watching television when a sharp stab of recognition hits her - the face she recognizes on the screen belongs to Nancy. Suddenly, the friend she thought she'd lost for good is within her reach. But does Nancy want to be found?

The search for her long lost friend forces Gaby not only to revisit her past, but could also shatter the course of her future . . .
