Veilfire: Book One of The Veilborn Chronicles

She crossed the Veil for answers.
He was the one thing standing in her way.
Lyra Vale has spent her life haunted by fire.
Ten years ago, an alchemical explosion stole her parents and left her scarred-physically and magically. Branded with forbidden veilfire, a volatile magic humans aren't supposed to possess, Lyra lives in hiding, apprenticing under one of the last known alchemists in the human realm. She only wants answers. About the fire. About her past. About the Veil-the mystical boundary separating the mortal world from the deadly fae lands.
When her mentor disappears under suspicious circumstances, Lyra risks everything and crosses the Veil in search of him. But the fae realm is no fairy tale. It's a world of shadow courts, ancient curses, and predators in silk and steel. And at the center of it all stands Caelum Thorne-cursed prince of the Shadow Court, a fae warrior feared even among his own.
Caelum was bred to be ruthless. Tasked with hunting down veilborn humans who illegally cross into his world, he has no patience for mortal trespassers. Until Lyra. Her presence ignites something dangerous in him-something ancient. She's supposed to be his prisoner. His problem. Maybe even his execution. But instead, she becomes his obsession.
Lyra makes him an impossible offer: her knowledge of veilfire in exchange for his protection. Caelum accepts-but not without a cost. Thrust into the heart of a court that wants her dead and entangled in a power neither of them fully understands, Lyra and Caelum must navigate a twisted world of lies, blood magic, and courtly betrayal.
But as the Veil itself begins to crumble and an ancient darkness stirs, the pair discovers they may be more than enemies. More than lovers. They may be the key-and the curse-that will either save or destroy both their worlds.
And no one walks through fire unburned.
