But, after years of bouncing from foster home to foster home, escaping to its tranquil setting, nestled deep in Swans Island, couldn't sound more appealing.

When her roommate suddenly goes missing, she finds herself in a race against time, not only to find her, but to save herself and discover the dark truth behind Sanctuary Bay's glossy reputation.
