When a cloud falls to earth, Calla sets out to find what lies beyond the sky. Father says there's nothing, but Calla knows better. Something killed that cloud; someone brought it down. Raised on legends of fabled skymen, Calla never expected them to be real, much less save one from drowning-and lose her heart to him. Who are the men who walk on water? And how can such strange creatures be so beautiful? Infatuated and intrigued, Calla rises out of her world in pursuit of a skyman who doesn't even speak her language. Above the waves lies more than princes and politics. Above the sky awaits the discovery of who Calla was always meant to be. But what if it also means never going home again?
