Half of the world has been conquered. Half lies in ruin. Fallen by the force of The Sea - a mysterious race whose origins are as obscure as their motives, except that they will not stop until their conquest covers the entire earth. In a remote region in the shadow of The Sea’s war, a boy named Galen grows up hearing voices from the ocean shore. His entire life, he has felt like half of him is missing. Misplaced. Lost somewhere just beneath the surface. Calling to him from the horizon in wind-flung voices. That is, until one day when he is confronted with surprising truths about his own origins, inciting him on a journey of discovery, ultimately leading him to the heart of The Sea.
