The Missing by Beverly Lewis

Season's of Grace - Book two. Grace Byler is working hard to keep the house running smoothly in the absence of her mother who left, not telling anyone where she would be. Since then, they have received one telephone communication and a brief letter just saying she was ok. Add an Englischer to the mix and Grace receives a surprising invitation. Her mother, Lettie, doesn't seem any closer to getting the answer she seeks, but is befriended by Amish woman Susan who unknowingly provides an answer to one of Lettie's questions. Lewis weaves mystery into the lives of the Plain people. Am looking forward to book 3. Sandy Penton
