Heir of Blood & Fire

If you devoured ACOTAR and Fourth Wing and need your next fix, this one is calling your name. Serena gets pulled into a fae world, held captive by a devastatingly beautiful king, and has to navigate prophecies, forbidden magic, and two men who would burn the world down for her. The worldbuilding is lush, the tension is delicious, and fair warning - book one of a series so prepare for that cliffhanger.
