Ethan has always been invisible—just another ordinary boy in a world that barely notices him. But when a celestial being crashes into his life—quite literally—everything changes. She is an angel, fierce and untouchable, bound by an ancient ritual that demands she share her divine power with a human. And fate has chosen Ethan. Thrust into a war between angels and escaped demons, Ethan and his reluctant partner must fight together against the rising darkness. But as they battle their enemies, something even more dangerous threatens them—feelings that should never exist between an angel and a human. Because if they fall in love, she will lose her powers, become mortal, and leave them both vulnerable. In a world where destiny is unyielding, Ethan and his angel must face an impossible choice—one that could doom them both.
