Reign of a King (Kingdom Duet, #1) by Rina Kent

Product Details

About the Book

Nothing is fair in war. Jonathan King is every bit his last name — powerful, untouchable, corrupted. He's also Aurora's dead sister's husband, and far older than her.

When Aurora first met him as a clueless child, she thought he was a god. Now she has to confront that same god to protect her business from his ruthless grip — never realizing that declaring war on the king will cost her everything. When Jonathan covets something, he doesn't only win, he conquers, and now he has his sights set on her, wanting to consume not only her body, but her heart and soul as well. She fights, but there's no escaping the king in his kingdom.

Aurora never wished to become a target in Jonathan's world, but now that events are already in motion and she's living under her sister's husband's roof, she intends to use the opportunity to piece together what really happened to her sister, who died eleven years earlier. The more time Aurora spends with Jonathan, the more she realizes he's a puzzle she can't quite solve — a tyrant, ruthless, calculated, and always in control, yet not quite the monster she once suspected, unless that's simply part of a much larger, calculated plan she has yet to see fully unleashed.

Aurora's own past carries its own darkness: her father, known publicly as the Duct Tape Killer, was finally captured after she turned him in to police at just sixteen years old — and now, from prison, he wants to speak with her. Meanwhile, Aurora begins receiving mysterious recordings that seem to be from her late sister, each one hinting that someone may have been trying to kill her before her death. The novel ends on a cliffhanger, continuing directly into Rise of a Queen.

Reign of a King is the first part of a duet and is not standalone; the entire duet is complete. The Kingdom Duet is a spin-off of Rina Kent's Royal Elite series, with Jonathan King being the father of Aiden King from that series — though it can be read independently, familiarity with Royal Elite adds extra depth.

Please note: This is a dark, mature adult romance containing BDSM elements, power-imbalance dynamics, and references to violent crime. Intended strictly for adult readers.
