@Vayvaction sorry this took me longer than expected! Brain was slow to wake up this morning.
Engagement/Pacing: I think you were really smart to introduce the childhood friends (Audrey & Vincent’s relationship especially) at the start, because it really adds a level of emotional depth to the work and gets quick investment from the reader. I was intrigued and found myself genuinely wanting to figure out how Vincent got to where he is! I think if a little bit more is explained in the opening paragraphs about the background of the kingdom, establishing early on that Riona is the princess of the Elven Kingdom and it’s the only elven kingdom, etc. It also would add a lot to see/learn more about her friendship with Audrey, since revenge for her death (plus the kingdom ofc) seems to be the driving force of the story. I think really hammering in her motivations and what she brings to the table, what she’s lost from the trauma, would make the plot absolutely take off and fly at a page-turning, stay up past bedtime reading, kind of pace
Characters: Vincent grabbed me really early on as an interesting character! I think it’s because Riona’s inner narrative spends time wondering about why he has changed and making it very clear that his behavior is confusing for her, so it brings him to life. Adonis, by contrast, really comes alive in his POV chapters, but can feel a little flat via Riona’s because we don’t get told much about his expressions, what she is thinking/wondering about him, how she interprets his behavior. And maybe she just doesn’t! But having her inner dialogue demonstrate it would help too. He’s a little confusing for me, because he is over-warm and then quickly swings the other way, so extra clarity on whether she thinks he’s full of shit/wearing a mask/or is just moody af would help.
As for Riona, I think more about her kingdom, her history, would get me more invested in her, but as it is I find her likable—but sometimes confusing. Like why she gets frustrated when she’s usually quite resigned, or there’s a bit that describes her as lacking any remaining pride, but she seems to have it still in my eyes! I think maybe a few extra paragraphs hinting in Chap. 1 what she went through as a slave to have what little life was left of her sucked out like that and leave her so broken would help round that off. Adonis and his motivations and how he thinks are crystal clear once we get to his POV in Chap 5, so fantastic job there!
General: I really like the opening of this and that it’s a different spin on the revenge trope and could have easily gone the regressor route but didn’t! It makes the plot feel really fresh and unique compared to other titles out there. Sometimes, I found myself wishing there were more breaks between scenes rather than a continuous flow, because I found myself a little bit confused re: how much time was passing and what I was supposed to be focusing on. Totally separate, I think using Riona’s emotional inner world and reminiscing as a tool could really make this shine! I think in Chapter 1 the reader might benefit from a small description or her perception of Adonis, because I did think he was a greasy, fat, pervy, old duke she needed rescuing from until I kept reading—don’t ask me why! I think it was just the setting, paying a ton for an ‘exotic’ slave, and the hand kiss. This plot, world, and characters have endless potential to explore and I’m so curious to see where you take them!
(Psst, early on there is a line where you accidentally use Adonis’ name instead of Riona’s, and I thought her name was Adonis for the rest of that page—I think it was Ch. 2? Whenever Adonis first talks to her in the manor—but I caught on the next time Adonis mentions her by name)
Take this with a grain of salt (aka take what resonates with you, leave the rest) because it's just the opinion of a chronically-online writer! I really enjoyed getting to know your characters and world, thank you for sharing
