A Silver Blur

Note: this is the first creative story I ever wrote, if you don't enjoy this ond it would be appreciated if you checked out some of my other stories.
A Percy Jackson fan fiction. Castle is mysterious and lives in the woods outside of Camp Half Blood. The tree she lives in is literally falling apart. What happens when she is found? Everything but the plot and my OC, Castle, belongs to Rick Riordan!
NOTICE: this is very old and I am not going to edit or make it better, be warned, it is terrible.
