Kusuo Saiki in... Heroes of Olympus

Kusuo Saiki was having a completely normal day. His friends- though he'll never call them that- were hanging around him, His mother was as kind as always, His father scatterbrained as ever, Even Satou was being his perfectly average self.
But the normal day ended when Kusuo put his head to the pillow that night. He ended up waking up somewhere completely unknown to him.
Now it's up to Kusuo to find a way home, while dealing with the new nuisances of this universe.

This is Book 1 in my "Kusuo Saiki in..." series. The books don't have to be read in order, though Saiki might use slight references from previous books in future books. (But since this is book 1, you don't have to worry about that yet)
The way I display Saiki's name will change depending on what universe he's in. Since Percy Jackson/Heroes of Olympus isn't placed in Japan- It'll be Kusuo Saiki. (First/Last) Hopefully it won't be too confusing! I'll try making it as obvious as possible.
The Disastrous Life of Saiki K, & Percy Jackson are (obviously) not owned by me, but owned by Shūichi Asō & Rick Riordan. I only own the changes to the original story! With that outta the way- I hope you enjoy this story. ^^
