Teen Spies has an interesting storyline and is difficult to put down! Written by mystery writer Jim Sargent in collaboration with his granddaughter, Audrey Deichmann, this story takes place in 1942 and involves a brother and sister and a neighbor’s nephew who suspect the nephew’s uncle may be a Nazi spy! How they attempt to learn more about their suspicions, the actions they take, and the danger in which they find themselves makes for an exciting story; a page turner, if you will. This story has it all: well defined characters, suspense, strong family relationships, and even a teenage crush. I hope there will be follow-up with the characters James and Nat.
