The Staff of Serapis by Rick Riordan
This is the second year in a row Mr. Riordan has gifted (blessed, teased, tortured, etc) us with a short story combining the worlds of Percy Jackson and the Kane Chronicles. In this segment it is Annabeth and Sadie who get to meet and join forces against a monster who is oddly connected to both worlds.
In this one we learn a bit more about who is behind the magic and theories are formulated as to why it is happening. It seems very much like Mr. Riordan might be a bit more than hinting at a major story line involving the Olympians and the Egyptians. Whether it is a single-title or a series of books, nothing has yet been confirmed.
Overall, Riordan Fans will salivate over this story, and the awesome bonus of being able to read a chapter from the final Heroes of Olympus book Blood of Olympus.
