The Divine Shallows by @alexandramtran has the intricate world-building of Throne of Glass and the political intrigue of Game of Thrones. It's about two fey sisters, one destined to inherit the throne, even though she never wanted it, and the other destined to be ostracized. Both want to change their destinies, even if that means changing the world they live in and uncovering secrets that are better left buried. Plus, this cover is absolutely gorgeous!
