A year after my divorce, I came face to face with my ex-husband in the pediatrics department of the hospital where I worked.

Moments later, the police arrived and arrested him.

As they led him away in handcuffs, Kirsten realized that she didn't fear his anger, but all the secrets she had kept hidden for so long.

That night, Kirsten and Kenneth checked into the old Hartwell fertility clinic, which had been abandoned years before.

There they found Dr. Elaine Hartwell injured and almost unconscious.

Before fainting, Elaine whispered that Kirsten's daughter was safe, revealed her name —Lily— and handed her a silver key.

On the wall behind her someone had written: "SHE WAS NEVER YOURS."

The key led Kirsten to a quiet house with a white porch, where six-year-old Lily lived with Mrs. Alden, the woman who had lovingly raised her after believing the embryo had been legally donated.

She had no idea that Lily had been stolen.

Looking at the little girl who had the same eyes as her, Kirsten realized that Lily already had a family.

He refused to destroy the only home the little girl had ever known.
