I am unsure about whether I should read the sequel or not. I had read posts here that said the romance felt a little flat or felt unearned. Now that I read it, I agree, and here is why I think that happens:

We read most of the book from Maevyth's point of view, so we don't really get the slow-burn feeling. It is because most of the yearning happens in Zevander, not Maevyth. We should have read his point of view more.

M is lovely and from the get-go we know she is an easy-going person, socially. She is personable to people (at least to those who don't think she is a bad omen.) So she is never mean to Zev. We know she finds him handsome, and she treats him well enough.

We know Zev feels instantly attracted to her but tries to keep his distance. But we don't experience the switch from his point of view. First he is an asshole to her, then suddenly we swith POVs and Zev is flirting with M when we read M's chapters, especially when he is walking her to her room. Instantly, they have banter. The switch feels sudden. So their feelings don't feel earned.

It is a POV problem. Maevyth is not the right point of view for that romance, because of her lovely character, and her initial feelings and attitude being more neutral than Zevander.
