The Eternal Knot. The Soul Weaver Trilogy, #3

With the Council reformed and the Soul Repair Shop thriving, Maya faces her greatest challenge yet. A dark, ancient curse known as the Eternal Knot is spreading, threatening to unravel the very fabric of the metaphysical world. The Knot was created centuries ago by the original Eternal Weaver - a powerful being who, driven mad by the grief of losing her young daughter Lily, trapped countless souls in an endless labyrinth of suffering in a desperate attempt to keep her child's soul from fading forever.
To break the curse, Maya and Daniel must descend into the heart of the Knot itself. Navigating a terrifying maze built from the pain and memories of thousands of trapped souls, Maya finally confronts the Eternal Weaver. Drawing on her own hard-won experiences of loss, failure, and the fear of losing Daniel, Maya connects with the Weaver's profound grief in a way no one else could. She teaches the ancient being that true love sometimes means letting go.
Through empathy and sacrifice, Maya helps the Weaver untangle the Knot, freeing the trapped souls and breaking the curse forever. The trilogy concludes years later, with an elderly Maya passing the shop down to her fully trained apprentice Lily. Having lived a life of profound purpose and love, Maya peacefully passes away, her soul rising to join the great weave of fate - leaving behind an enduring legacy of hope, compassion, and repair.
