Secrets of Castle Creet

When a sporadic trip between two best friends, Carla and Adria, gets bombarded with a series of mysterious events, Carla can't help but wonder who is playing tricks on her. But are they really tricks when a tiny whisper keeps telling her exactly where they plan to visit and ends up following them to their Irish destination? Carla tries to push it aside when she finds out her best friend's mom finds a letter talking about a family key. Adria learns her ancestral ties to Ireland are bigger than she thought when she hears of an old castle home that is now abandoned with secrets of its own. They take on the trip to find out answers and expose the truth. What happens while they are in Ireland? Whom do they meet? And who were the Gallaghers?
