Once upon a Demon's Heart

Cruel Fates Duet, Book 1

By: K. M. Moronova

Narrated by: Madison Mitts, Theodore Zephyr

This is no fairytale; it's the yearning and guilt of two burdened hearts that will leave you breathless.

Alira, a devoted demigod knight, has found herself trapped in the throes of a brutal curse—a time loop in which the demon kingdom's Blood Knight kills her every time. She is haunted by the attack she led on the innocent village of Thornhall, and her guilt consumes her from the inside out. After the twentieth time loop, she has finally had enough. Something has to change, lest she die at the Blood Knight's hand for the rest of time. A choice she hopes she won't regret—one to end the war between demigods and demons. Alira is shocked when she realizes that she's marrying the very knight who has slain her so many times.

A daughter of Venus and a duke of demons. Their love is both cursed and destined—a marriage to save the fragility of their kingdoms.

Kalel is as cruel as they come. A devourer who survives on the gilded blood of demigods. He wants to hate her as much as he did when Thornhall fell, but he finds himself warring with his heart over his emotions for her. Together, they unravel the truths of Faultore, that perhaps not everything is as it seems. The gods may be pulling more strings than they should.

It's not a question of what love can conquer; it is a matter of what they are prepared to demolish in the path of it.

Narrated in duet style.

3.5 Stars ⭐️

When I say that I went into this book blind, I mean that I just hit play on my Audible app without seeing what was up next in the que. I hadn't even looked at the summary so I was completely clueless on where this story was going.

Basically we meet our FMC Alira, a devoted demigod knight (even though I really had no idea what that entailed). She is going through some type of time loop (think Groundhog Day) where she is apparently fighting and being killed by this certain Demon Knight EVERY SINGLE TIME. I gathered the demons were their enemies - she is a demi-god - and the two factions are at war.

Things happen and Alira volunteers to enter into a marriage agreement with the demons (still not really sure why she did that) but it will supposedly create the truce that both sides need. As things evolve, we begin to learn that there is actually history between these two characters and things begin to get interesting.

This is the first book and the end of this book does set up the events for what ever is going to happen next. As usual in stories like this, there are gods at play and whenever that happens, it is usually because said gods are either bored, or they want to stir up trouble. Neither of those possibilities are good.

I hope that there will be a bit more thorough building in the next book and maybe some history to go along with it as well so that we can get a better understanding on the "why" what happened to each of them as children had to happen.
