The Ember Rite

Five ancient clans of sentient cats have ruled the world of Ferrath for ten thousand years, each guarding their own magic and their own territory. The Ashenclaw control fire. The Duskmantle control shadow. And the line between them has never been crossed. Until Kael. On the morning of his eighteenth birthday, Kael undergoes the Ember Rite - the sacred ceremony that bonds every young Kindled to their clan's power.
But when his Flamemark blazes white instead of orange, the Elder Council's fear is immediate and absolute. White fire means only one thing: Ember-Unbound. A bloodline so dangerous it was supposed to have been erased from history. A bloodline that carries the gifts of all five clans at once. Before the council can act, a mysterious stranger named Venn emerges from the mountain's hidden passages with a warning - and a secret that changes everything.
Kael's mother did not die from a failed Rite. She was stopped. And she spent twenty years before her death building a plan that only Kael can finish. Somewhere across Ferrath, four others just like him are coming of age. One in every clan. All carrying the same forbidden fire. All running out of time. Kael has been given one year to prove that an Ember-Unbound in control is not the catastrophe the councils fear.
One year to cross five hostile territories, find four strangers, and complete a mission that was a hundred years in the making. The last time someone tried, thirty thousand died. This time, Kael intends to get it right. The Ember Rite is the first book in The Pyremark Sagas - a dark fantasy trilogy set in a world of ancient feline civilizations, forbidden magic, and the dangerous truth that some powers were never meant to have fences around them.
