I Married the Dragon I Killed

Cast out by his family for refusing a betrothal to the dreaded Red Dragon Valdrova, Ferda Rosnova chooses a path of blood and vengeance. After claiming Valdrova’s heart—a heart she surrendered without resistance—Ferda ascends to godlike status. However, a glimpse into the depth of the dragon’s ancient despair renders his triumph hollow and reveals the utter emptiness of his ambition. Armed with his new power, Ferda turns back time to start over. This time, he won't run; he decides to embrace his fate and marry the dragon who willingly gave him her heart.
