One option for young readers is 'The Cooper Kids Adventure Series' by Frank Peretti. These novels follow the adventures of Jay and Lila Cooper as they travel around the world and encounter all sorts of mysteries and dangers. They also learn about God and His power in the process. 'The Imagination Station' series is another great choice. Kids can go on virtual adventures through time and space, meeting historical figures and learning about Christian faith in different eras. 'The Secret of the Hidden Scrolls' series is also a good pick. It has kids finding ancient scrolls and going on adventures to unlock their secrets, all while learning about the Bible and Christian teachings.
