This book holds great appeal for the target audience, kids aged 8 - 12. It has a graphic novel quality to it that would appeal to kids that love comic books, while the arrangement of the text provides structure, but also gives younger readers sections to focus on without being overwhelmed with a long bunch of words. All together, the appearance of the book is perfect for kids.
As far as the content, I love it! I love devotional books or other books geared for kids that I can learn from and this one offers a lot of information in a very user friendly format. Cooley takes well-known people from the Bible and tells their story in a way that is easy for kids to understand. Readers get to know Noah, Moses, Jonathan, Daniel, Jonah, and many others. But the best part is that Cooley draws connections from the heroes to the kids. For example, he talks about how Jeremiah thought he was too young to be used by God and helps readers to see that God can use anyone.
The best part of this book is that after readers learn the story about the hero from the Bible, there are encouraged to internalize the lessons learned and make their own Battle Plan, which is a short exercise to apply the lesson to their life. Most of the Plans are quite short, consisting of memorizing a verse or spending some time in prayer.
I think this is a great book that is perfect for the 8-12 age bracket. Younger readers can gain experience working through a devotional independently and start to develop individual Bible study skills. If you are looking for an awesome devotional for a tween, this is a great choice!
