Heart of the Castle

Katie didn't expect the most haunted castle in Europe to hold the answers to an incredible family secret. During a summer studying abroad in Transylvania, she finds herself at the gates of Bran Castle, the one time prison of medieval ruler, Vlad "The Impaler." More recently, in life, Bran Castle was home to the King and Queen of Romania. In death, the castle was home to just the queen's heart.

Now, along with 15-year-old Katie's friends Cam, John, and new roommate Ruth, she uncovers a century-old mystery and a terrifying adventure. Will haunting spirits from the past lead her to safety and treasure, or push her into the hands of a deadly ex-secret policeman hunting for the same prize?
