Where Dragons Cry - Where Dragons Cry, #1

From the ruins of a Welsh castle to the fortress in its full glory, Architect Cassian Bevan has been pressed by his school friend into revisiting the castle that has haunted his chidhood, now as an adult he returns, only to hear a cry that tears him from the world he knows into a version of the past that changes his life forever. But can his unexpected love for the beautiful and wild Arianwen Cadogan keep him in this realm? Or can he be snatched back by the same force to the modern realm, where his broken relationship with his mother and cold childhood still pumps ice through his veins.
Cassian's determination to find the truth and discover the power that delivered him to this realm of old, how to remain there and what secret gifts he inheirited from his absent father along with the true power held in his lungs, leads him on the journey of a lifetime, through realms to face dragons and find himself and the love of his life on the way, but now he's found her... can he stay in her world?
