I decided to be nice since I did enjoy most of the book, but this 4 star is actually a 3.5 for how much the ending pissed me off. 
 I should say, that I was not a fan of the main couple, and I think Javier would be better off with Elezar, who is infinitely less high maintenance to Kiram. But that silliness inside, the world-building in here is as gorgeous as Wicked Gentlemen. The handling of the various religious sects and convoluted history is crisp and the settings completely immerse you in the character's world. I also loved the ongoing secret about what White Hell actually is and what curse is haunting the Toresal descendants. As with Scarlett and the White Wolf, this is considerably more than just m/m romance. As far as the characters, I thought they could have been fleshed out a bit more and they seemed to jump around a bit, but I liked Javier and Nestor well enough to keep me satisfied. 
 But I'm not entirely sure how I feel about the abrupt ending... A book shouldn't read this much like a serial. Disappointing since I otherwise highly enjoyed it.
