Seventeen-year-old Amber has spent her entire life hidden away in an isolated castle on the windswept cliffs of the Scottish Highlands. Raised by guardians who refuse to answer questions about her parents or the world beyond the mist, she has always sensed there is something different about her—something even they fear.
When she's sent to a boarding school in Edinburgh just before her eighteenth birthday, Amber finally begins to experience friendship, first love, and the freedom she's always dreamed of. But strange blackouts, vivid nightmares, and impossible events soon convince her that the truth about her past is far more extraordinary than she ever imagined.
