SCREEECH! The tires of the Marigold County's mailman truck skid across the roads of the Marigold Estates. Some 45 trailers were just waking up as 15 year old Percy Jackson walked out the door, straight into a puddle. Percy's Monday hadn't started off well, considering his dad had left just two days ago. All he left was a note saying he needed time, and didn't know when he'd be back. To Percy, it wasn't a great way to wake up that morning.

And walking to school that dreary September morning wasn't great either. The sky was the kind of gray that everyone hates going out into. The trees were looming over everyone, as though they were watching his every move. The large brick building that lay ahead of Percy was ominously creepy, and the sidewalks leading to it were a dark grey, and Percy's feet sloshed in the mud along the grass.
