A Percy Jackson, Harry Potter, and Keepers of the Lost Cities Crossover. Harry Potter wakes up in a strange room painted the colour of the sea. Percy Jackson wakes up in a literal princess castle, glistening with gems. Sophie Foster wakes up in a gloomy castle, lined with red, green, yellow, and blue. Hope Viotto wakes up in the multiverse with a role she might not be able to handle. They don't remember anything, except that they don't belong. I don't own any of the characters, except for Hope and the plot.
