I liked this way more than I thought I was going to purely because my expectations regarding YA fantasy are appropriately tempered and the vampire lore that was constructed had such a different take on vampires within the subgenre that I can say with some satisfaction that I have not encountered before.

There was proper enemies-to-lovers with all of the expected explosive sexual tension and it was a lot more nuanced and effectively believable compared to how YA novels typically depict that trope. 

I liked the worldbuilding but still think it could be further developed. 

And I found a lot of the relationship dynamics to be inconsistent - the romance was good if a bit less fleshed out than anticipated based on how strong the lead characters are depicted, but the friendships were quite weak in contrast and seemed more convenient than anything substantial. 

The sibling dynamics were also tackled in a manner that I understood with respect to Kidan and the importance it held in her and how it impacted her choices in terms of her conduct and the overall plot, but I didn't quite feel the attachment between the sisters. It remains to be seen how their relationship will be translated and developed in the sequel as we will actually be able to get physical interactions between the sisters as opposed to a one-sided perspective in Kidan.

I'm definitely engaged enough to continue with the series, and will be reserving a library copy for my perusal upon it's release.
