Sarah and Hannah have been best friends since childhood. Nothing and no one can come between them—except, perhaps, each other.

They believe they can have it all, and for years they try, navigating the milestones of life—careers, marriages, children, and the choices they make that lead them down very different paths. But when the man they both love dies unexpectedly, everything changes, and the cracks begin to form.

They retreat to a secluded mountain resort in Spain, run by their troubled friend Skye. But instead of peace, they uncover secrets and betrayals that threaten to shatter everything they thought they knew about each other.

As the past unravels, will their lifelong friendship be destroyed, or is their bond strong enough to survive the bitterest betrayal?
