This comicbook style devotional features well-known bible heroes like God, Abel, and Jonathan, as well as some lesser known bible heroes like Joash and Gideon (which I thought was pretty cool). It also features a couple of girls (Ruth and the Jewish Slave Girl); however, I don't really think this book would appeal to most girls. It's quite masculine and I totally love it--for my little guy. My son is only 6, but I'm saving this book for him for when he's a bit older. He's going to love it! It's got a comic book, superhero kind of presentation to it and that will definitely appeal to him. This is such a unique devotional, and it's nice to see a very boyish devo for boys older than... say... 3. Not something I can recall coming across before. It's cool and it reveals an important truth: while Captain America and Wolverine are pretty awesome superheroes, there's no superhero as awesome as Jesus, and the other heroes in the bible not only did great things for God, but they were flawed people just like us. Flawed, but with a faith God could use to turn them into heroes... and He can do the same with us.
