The Disappearing Stranger — Lois Walfrid Johnson

If she told her new family what she saw, would anyone believe her?

Her Irish father having died in a construction accident, Kate O'Connell and her mother are left to struggle alone in the Minneapolis of 1906. Deciding her mother needs help, twelve-year-old Kate goes to pray with their pastor about getting her mother a new husband.

But when God answers their prayers, even Kate is not prepared for the changes. Her mother's remarriage involves becoming part of a Swedish family with two brothers and one sister on a farm in northwest Wisconsin. Such a big change is made harder when Anders, who is also twelve, gets mad at Kate and seems determined to make her life miserable.

As conflicts erupt with Anders, strange occurrences begin to happen around the farm. Kate is convinced she sees someone lurking about, but why? Are their lives in danger?
