I can't recommend 'A Court of Thorns and Roses' by Sarah J. Maas enough. It's a perfect blend of magic, adventure, and swoon-worthy romance that keeps you hooked from the first page. The chemistry between Feyre and Rhysand is electric, and the world-building is absolutely immersive. Another favorite is 'Crescent City' by the same author, which mixes urban fantasy with heart-pounding romance.
For those who enjoy a bit of mystery with their love stories, 'The Cruel Prince' by Holly Black is a dark, twisty tale of enemies-to-lovers set in the treacherous world of faeries. The tension between Jude and Cardan is deliciously intense. If you're looking for something lighter but equally enchanting, 'Serpent & Dove' by Shelby Mahurin offers a fun, witchy romance with plenty of banter and action. These books are perfect for teens craving a mix of fantasy and romance.
