Once Upon a Demon’s Heart/Once Written in Gilded Blood

SpoilerBook Review

Just finished this duology and I have thoughts I need to share.

{once upon a demon’s heart} {once written in gilded blood}

Spoilers ahead! Spicy book so expect some reference to that too.

>! So first thoughts - easy read and great if you like going on just the vibes.

Emotional in places throughout both books and a decent level of spice. Was not expecting there to be knotting in this. And also the description of his dick being so big that it continuously enters her womb when he’s fully in and makes her belly move, were interesting choices. And I understand why she needed the healer every time after they had sex in the first book. But did she not need that in book 2? The time jump between books is frustrating because there’s clearly been significant relationship development even though Kalel is still lying and Alira is suspicious of him.

Where did both of their heat cycles go in book 2?! What was the point in them going into heat at all other than for their first dubious sexual encounter. Yes, Kalel creates the potion to help her but this just feels like a convenient way for the author to be like “yeah I got bored of that” and Kalel never goes into heat at all again?

My biggest gripe is that book 2 made sure we knew about Alira being a really rare demigod in that her father was a demon and her mother Venus, but Alira never finds out she’s half demon. What was the point in even mentioning that? Also, book 1 was laying ground work for us finding out who Kalel’s father was, only for that to be never brought up again. !<

I have other issues but these are my main ones.

I actually enjoyed these books but they could have been strengthened in so many ways to become knock outs. The premise of the story is so interesting but ultimately fell a bit flat for me given what I talked about above.

Any thoughts?
