Fairies have always existed in secret, without a kingdom of their own, living side-by-side with humankind. But, when one of his own children is murdered, King Oberon asks his surviving daughters -- newly minted NYPD detective Charli and wingless black sheep Lucy -- to find her killer amidst the citizenry of New York. As Charli and Lucy delve deeper into the mystery, they begin to discover the extraordinary measures their father has taken -- some clever, some desperate -- to keep an entire people hidden in an increasingly treacherous world.
For Charlie and Lucy, unmasking their sister's executioner will mean confronting their own blood-drenched legacy.
