After you were gone - Vikki Wakefield

In a busy street market, Abbie lets go of six-year-old Sarah's hand. She isn't a bad mother, just exhausted. When she turns around, her daughter isn't there. Six years later, Abbie is in love and getting married. But her fragile peace is constantly threatened: not knowing what happened to Sarah is like living with a curse. Then she receives a phone call from an unknown number. A man claims to know what happened to Sarah, but if Abbie tells anyone or fails to follow his instructions, she'll never find out the truth. After You Were Gone is an edge-of-your-seat thriller that poses the question: How far would you go to find your child?
