Danny Orlis and the Mysterious Visitors (Paperback) (ISBN-13: 9798889360605)

Del, Doug, and DeeDee Davis and their cousins Phil and Marie head up to the Northwest Angle to spend part of the summer at their Uncle Carl's fishing camp.

Police investigations, middle-of-the-night baseball games, bank robbers, and a kidnapping make this a high-action and inspiring read!
