The characters of Spy School meet the characters from the Heroes of Olympus and Percy Jackson. Read to find out how this all goes down. For the thumbnail, I just chose a random picture. I thought it was pretty funny. Yes, I know, I'm terrible with descriptions but that's all right. Also NONE of the characters belong to me. They belong to the authors of Percy Jackson and The Olympians/The Heroes of Olympus and of the Spy School series. These are two of my favorite series so I really recommend them!
