Fourth Wing has heat, but some readers want more. These five books deliver the same enemies-to-lovers tension and fantasy stakes with the spice turned up. All are shelved as adult fantasy romance.
A maiden, a forbidden guardian, and a mythology that keeps twisting. The spice is explicit and frequent. Six books and counting.
Twin sisters enter a magical academy where the heirs want them gone. Enemies-to-lovers with heavy spice and a very long burn.
A human woman with no magic enters a vampire tournament. The slow burn is exquisite and the payoff is worth the wait.
A human raised by vampires enters a deadly competition. The romance builds through combat and trust. Sharp and well-paced.
A witch and a demon prince in historical Sicily. The tension between them crackles. Each book escalates the heat and the stakes.
