The Shattered Throne. The Soul Weaver Trilogy, #2

Six months after claiming her place as a soul repairer, Maya Hart is summoned before the formidable Weavers' Council. The metaphysical world is in crisis: a rogue repairer named Theron is breaking souls for profit and creating beings of pure chaos. To Maya's shock, Theron is not just any rogue - he is her grandmother Elara's former master, a man deeply scarred by Elara's past betrayal. Determined to uncover the truth and stop the destruction, Maya, alongside Daniel and Balthazar, journeys to the Shattered Isles, a desolate prison where broken souls are left to fade.
There, they uncover the dark underbelly of the Council's regime and realize that Theron is as much a product of the Council's own corruption as he is a villain. Maya faces a defining choice: destroy Theron as the Council demands, or attempt to save him. Choosing compassion over obedience, Maya sparks a revolution. In the conflict that follows - the Weavers' War - Maya and her allies fight to tear down the old, corrupt system.
They succeed in overthrowing the Council, rescuing her long-imprisoned grandmother Elara, and establishing a new order built on healing rather than punishment. As the dust settles, Maya takes on her first apprentice, a gifted young girl named Lily, ensuring the cycle of repair will continue into the next generation.
