Bound by Breath: A Slow Burn Enemies-to-Lovers Romantasy in a Dying World by Virginia Vale

The people of Azilia are suffocating. Without the enchanted Breath Willows, they would already be dead. And with every passing day, fear and greed over the dwindling air drive humans to hunt witchkind to the edge of extinction. Lira never expected to be accused of witchcraft. Her arrest draws the unwanted attention of Gregor Thorne-feared commander of the king's Oathsworn guard, a man who prides himself on hating witches. But when Lira uncovers a secret powerful enough to upend the kingdom, Gregor is forced to question everything he thought he knew about her. Across the sea, in exile, feared warlock Archmagus Luca Vaux waits. Determined to restore the great witch covens and topple the human king, he believes Lira is the key. Only she can retrieve the Breathstone-the relic sealed by the gods that could save Azilia from collapse. But Luca has not told her the price. Torn between the life she longs to return to and the destiny she cannot escape, Lira must choose: run from fate, or claim it. But when her sworn enemy becomes the one she cannot live without, survival and love may demand the ultimate price.
