What would you do if you discovered that aliens have been living on Earth? And then what would you do if you learned those aliens were in a whole lot of trouble from another alien race? Those are the questions in Inner Terrestrials and the Gireens: The Discovery that two human teenagers face when they discover a beautiful underground world of Inner Terrestrials. Under attack, these beings fled their home planet and rebuilt underground on Earth. Now, they have new allies in the human teens. This is just the beginning of the teens' adventure. They're not just soldiers in an intergalactic war but still regular humans, facing fears and doubts, the confusing complexity of the underground world, and the challenges of teamwork. But they dig deep, drawing on courage and acceptance-and yes, along the way, even a little bit of fun. This first book in a new sci-fi/adventure series is perfect for readers aged 9-13.
