To Kill a Kingdom

Probably this is more fun if you like romantasy more than I do. 
I enjoy stories with two POV but there was no signal for who was the focus of each new chapter - which was fine while it was usually trading off with each new chapter, but then got a tad jarring when it switched to longer passages from each perspective. 
I liked the snarkiness and enemies to lovers trope is fine, but the prince just seems dumb for not figuring out her identity sooner. The romance itself seemed slapped on because of course there had to be romance, not fleshed out so it'd be believable. It dragged by the middle, I nearly DNF'd.
