Soulfire. Soulfire Chronicles, #1

When your soulmate is your sworn enemy, love becomes an act of treason. Elara Thornwood has spent her entire life preparing for one thing: to never need anyone. As a powerful Fire Weaver and archivist at the Grand Archive, she's built a quiet, controlled existence cataloging magical history while kingdoms burn around her. Then her soulbond awakens. The cosmic connection that should complete her is instead tearing her apart-because her fated mate isn't just from the enemy Ash Kingdoms.
He's Prince Kael Ashenblade, heir to the throne of the very people who have slaughtered her family for generations. Kael is dying. The bond rejection is consuming him from the inside, and he has weeks-maybe days-before his own magic destroys him. His only chance at survival lies across the Sundering Mountains, in the hands of a woman who has every reason to let him die. When they finally meet at the border between their kingdoms, exhausted and half-dead, they face an impossible choice: complete the bond and become traitors to everything they've ever known, or fight fate and guarantee their own destruction.
But the ancient fortress where they take shelter holds secrets that could change everything. Evidence that their kingdoms were once united. Proof that the centuries of bloodshed began with a lie. Now Elara and Kael must decide: Will they hide their bond and live as fugitives? Or will they return to their kingdoms and dare to imagine that two people bound by fate could be strong enough to end a thousand-year war?Perfect for fans of Fourth Wing, From Blood and Ash, and A Court of Thorns and Roses, SOULFIRE is an enemies-to-lovers romantasy about choosing love over loyalty, and finding the courage to rewrite history.
