Every god is destined to love once—except Death. For thousands of years, the God of Death has been Heaven's perfect weapon, collecting souls without mercy and without a heart of his own. He was never meant to love. Until one mortal woman unknowingly thanks the lonely god who stands unseen at every funeral. In that impossible moment, Death's heart begins to beat. Across Heaven, the stars dim, miracles fail, and the divine power sustaining every immortal starts draining into the woman who now carries the Heart of Death. Before sunrise, the gods sentence her to execution. But Death has carried billions of souls into the afterlife. For the first time in eternity... he refuses to take one. Hunted by Heaven and pursued across a world where every god wants her dead, a lonely immortal and an ordinary mortal must uncover the greatest lie ever told: the gods built their kingdom on stolen souls, and their forbidden love may either destroy creation... or finally set it free. When Heaven declares love the greatest sin, even Death must choose a side.
