Cold-Case Christianity for Kids by J. Warner Wallace and Susie Wallace with Rob Suggs*

Using second person, Mr. Wallace places the reader right in the story.
With other characters in the story, the reader is trained in the detective training academy as cadets.  Detective Jeffries instructs the students how to look at a crime scene like a detective.  As they solve a skateboard mystery, they also "solve" the mystery of Christianity to determine if it is true.
*Highly recommend.
-I own this book.
Reading this version makes me want to read Mr. Wallace adult version -Cold-Case Christianity (which he recommends to parents who have bought this book for their children).
