Girl Who Came Back - Kerry Wilkinson - Bog

"When six-year-old Olivia Adams disappeared from her back garden, the small community of Stoneridge was thrown into turmoil. How could a child vanish in the middle of a cosy English village? Thirteen years on and Olivia is back. Her mother is convinced it's her, but not everyone is sure. If this is the missing girl, then where has she been--and what happened to her on that sunny afternoon?"--Amazon.com.
