Heart Stone - Legends of the Fallen, #8

USA Today and International Bestselling authors J. A. Culican and H. M Gooden presents a new epic fantasy adventure full of dragons, magic, and legends. Knowledge could be the one thing that saves them all, or destroys them.  Rhin now knows that there are objects hidden throughout the world that will somehow help them save Lynia. She doesn't know what all of them are, and the Library is playing coy, only revealing parts of the information.
It's as if the Library is testing her.  With the Soul Goblet in hand, she now has to locate the Heart Stone, but there are enemies everywhere, including inside the Library itself.  The deserts of the Northern Territories provide a whole wealth of new dangers as the clues the Library provided unravel, leading them to dangerous locations where they're surrounded by people who want to use them or kill them or both.  Rhin must find the Heart Stone before the agents of Dag'draath do.
Or the world might become the nightmare they've always feared.      "This is the epic fantasy series of the year! A whole new world full of magic, dragons, darkness and unlikely heroes..." - USAToday Bestselling Author, Melle Amade ?????
