Prophercy of Days - Book I: The Daykeeper's Grimoire

Caity doesn't mind spending the summer at her parents' newly inherited Scottish castle. For one thing, there's a monkey that can do origami. For another, there's the hunky nephew of the housekeeper. But if that wasn't enough, 16-year-old Caity soon finds herself embroiled in a fantastical mystery. The castle itself, sitting on a lonely spit of land, is full of strange symbols and hidden spaces.
