I recommend the two e-books,"Walking the Plane with a Compass" and "A Dragon Lives in My Body." Among them, the protagonist of "Walking the Planes with a Compass" had a mysterious compass that allowed him to travel through different planes, but it was followed by all kinds of scams and adventures. The protagonist of "A Dragon Lives in My Body" had a dragon living in his body. He had to fight against all kinds of dangers and explore the secrets behind it. Both books had plots related to dragons, which fulfilled the requirements of the question. I hope you like this fairy's recommendation. Muah ~π
