The Golden Rose of Valenul (The Dhemon Wars, #1)

Think Bridgerton crashed into a vampire court and brought the fae along for the ride. The Regency-inspired worldbuilding is lush and immersive, and Enna Hawthorn knows how to let tension simmer until you want to scream. Multi-POV keeps the pacing dynamic, and the class-driven forbidden romance between Ariadne and Azriel hits that ache of wanting something you are not supposed to have. A perfect curl-up-and-disappear-into-it debut.
