Cruel Beauty by Rosamund Hodge
My rating: 5 of 5 stars
Nyx was raised to marry (and destroy) the demonic leader of her land. The Prince of Demons gives people bargains that give them what they want while destroying them in the process. Nyx and her twin sisters were the result on one such bargain. Nyx is resentful of her family for choosing her and not her weak-willed sister to marry the Prince. However she soon acccepts her fate and decides that instead of passively waiting for her new husband to kill her, she will destroy him and his strange castle first.
I devoured this book in one sitting and was left with a huge book hangover afterwards. Ignifex is oddly compelling from his very first appearance in this book to the last. I enjoyed this book immensely and recommend it to anyone who enjoys fantasy.
(NOTE: The ending is a bit flat but I was just so glad to have my HEA that I was totally okay with looking the other way)
