The Hell of the Nine Realms: Book 1: The Mystery of the Odinsons

Experience this adventure through the eyes of Raelin Connelly, daughter of Thor, as she trains with her lifelong friend David Reeves - Son of Odin. However, things are not as they seem, as Raelin comes to see. David has gotten much more powerful over the last four years due to training in the Original Universe. But that's still not it. There's something different she hasn't seen in him before. He seems to be becoming darker and more... Animalistic. And if that wasn't enough, a giant serpent seems to be terrorizing her school. Will Raelin and the others solve this mystery in time? Or will all crash and die?
NOTE: This story is written, for the most part, in English. But there will be times certain people (mostly David, Lizzy, Jamie, and supernatural beings) will speak in different languages. These different forms of dialect will normally be either Norwegian, Old Norse, Greek, or Ancient Greek.
NOTE: If this reminds you of anything, you are correct. This story (like 50 Shades of Grey (can't believe I'm mentioning that)) started out as fan fiction, as did the sequel story, before it began to evolve into its own thing by the end of the sequel.
