The Oracle of Dusk by Elyse Thomson

An oracle should know better than to fall for a doomed king.

Aurora is a historian—not a prophesied hero. But the day she finds her first artefact, destiny pits her against the primordial monster that has repeatedly destroyed her world. Cornered by the beast, she escapes death when the artefact sends her to the ancient past and gifts her one chance to kill the monster before it’s unstoppable. Except it also lands her in the arms of King Theron, a handsome schemer infamous for his tragic fate.
Theron is a bad man but an excellent king. When a battlefield mishap sends him to an enemy queendom in chains, the last thing he expects to find is a beauty with the knowledge to save his kingdom and crush his foes. Tempted by Aurora’s uncanny foresight, Theron vows to possess her at any cost.
Aurora’s only hope to defeat the monster in the ancient past is Theron’s army. With her world’s future at stake, she knows better than to succumb to his seduction, yet finds herself hopelessly drawn to him. But as she awakens magic that torments her with visions of predestined tragedies, Aurora begins to fear her heart is as doomed as the man—and world—she’s trying to save.
Inspired by The Legend of Zelda, The Oracle of Dusk is the first epic fantasy romance novel in the Cycle of Calamity series. If you love height differences (understatement), time travel, and fated romance, escape into The Oracle of Dusk!
