"After losing both their parents, Bristol Keats and her sisters struggle to stay afloat in their small, quiet town of Bowskeep. When Bristol begins to receive letters from an "aunt" she's never heard of who promises she can help, she reluctantly agrees to meet -- and discovers that everything she thought she knew about her family is a lie. Even her father might still be alive, not killed but kidnapped by terrifying creatures to a whole other realm -- the one he is from. Desperate to save her father and find the truth, Bristol journeys to a land of gods and fae and monsters. Pulled into a dangerous world of magic and intrigue, she makes a deadly bargain with the fae king, Tyghan. But what she doesn't know is that he's the one who drove her parents to live a life on the run. And he is just as determined as she is to find her father -- dead or alive"-- Provided by publisher.
