Whispers of the heart… Yet, the more Eden learns about Darcy, the more she realizes that all is not as it seems, and she begins to suspect foul play behind Peter's and Adam’s fates. As the tension around them escalates, Eden’s mysterious dreams become more and more frequent. Can Eden listen to what her heart is trying to tell her before it is silenced forever?
