Abduction (A Shefford-Johnson Case #1) by Wanda L. Dyson

Even as she breathes out her baby's name, Karen Matthews knows that her worst nightmare has become a reality. Her seven-month-old is gone, stolen during the night. When the police call a famous psychic, Zoe Shefford, to use her mysterious "powers" to locate the child, Karen hesitates. When her husband suddenly disappears as well, Karen becomes the prime suspect. Apparently, God has forgotten about poor Karen Matthews, left to mourn the loss of her baby, her husband, and even her faith-or has He? That's what Karen-and Zoe-must find out before it's too late.
