Vow of Eternal Night by Lily Crozier

Clara Wagner has always known that monsters are real, and the worst of them is Prince Raleigh of Rostenburg.

But when he decides it’s time to marry, Clara inadvertently finds herself at the center of his attention.

Forced to accept Raleigh’s proposal, Clara would do anything to escape her fate. So when the prince provides an ultimatum—lift his vampiric curse before the end of the year, or become his bride for eternity—Clara knows what she must do.

Heal the prince. Stay alive. Try not to fall in love.

Vow of Eternal Night is a slow-burn, enemies-to-lovers, gothic romantasy about the lengths people will go to for love, and the many faces monsters can wear.
