Emily, gone by Bette Lee Crosby

In a small town where people leave their doors unlocked, a baby disappears from her crib one night during a music festival where hundreds of strangers have filled the town. Rachel and George Dixon, the baby's parents, are desperate and heartbroken, trying to live on after no sign of their daughter is found.
Meanwhile, Vicki, a woman suffering from her own loss of a stillborn baby, has claimed this baby as her own. Her boyfriend, Murphy, is fearful for Vicki's fragile health and allows her to keep the baby while trying to figure a way to convince Vicki to return her. When the Dixon's finally find their child in a chance encounter, everyone's lives are forever changed in a beautiful ending.
Although I sympathize with Vicki's loss, her justification for taking Emily was selfish and ridiculous. I was glad she was only in the first part of the book. I really felt bad for the innocent victims, Angela and Kenny at the end of the book and was glad they found a good compromise with Emily's real parents.
