They bring Mirelle Ashwyn to the holy city in chains, expecting a confession, a pyre and a tidy victory for the Light. Instead, one drop of her blood touches Sir Caelan Veyr's sacred relic?and binds the condemned witch to the knight sworn to deliver her to judgement.
Caelan has spent his life serving the Radiant Order without question. Mirelle has spent hers surviving what its priests call mercy. When their blood forges a magical bond that makes separation unbearable, captor and prisoner are forced to flee together while the Church brands them enemies of the realm.
Every mile exposes what they would rather keep hidden. Caelan feels the terror behind Mirelle's defiance. Mirelle sees the guilt buried beneath his polished armour. Their enemies-to-lovers slow burn becomes more dangerous with each shared wound, reluctant kindness and truth neither can conceal.
But the corruption spreading across Aurelia may not come from forbidden magic at all.
As broken wards fail and sacred relics awaken, Mirelle discovers that her curse may be tied to a history the Church erased. Caelan must decide whether obedience still deserves to be called faith?and whether protecting the woman he was ordered to condemn can ever atone for the suffering carried in his name.
Their forced-proximity magical bond offers no privacy and no easy escape. Between a protective hero and strong heroine, forbidden desire grows into a choice that could cost Caelan his rank, Mirelle her freedom and both of them their lives. Yet trusting one another may be the only way to stop a wound in the realm from tearing open.
Blending forbidden-love fantasy romance with a tortured-hero redemption arc, a strong heroine wielding forbidden magic and the emotional intensity of low-spice adult romantasy, Vow of Halo and Thorn is a story of shared pain, earned trust and two enemies who may become the one thing their world was built to prevent.
And beneath the prayers, executions and gilded lies of the holy city, an older vow is beginning to wake.
