The Shifting Echoes of Infinity follows Livia Strathmore, an ordinary corporate worker in the futuristic city of Althera, who suddenly gains the ability to shift between alternate realities. As she navigates fractured worlds, some utopian and others dystopian, Livia discovers a mysterious mark on her wrist that connects her to the multiverse. Along the way, she encounters versions of herself, cryptic shadowy figures, and Zorn, a time traveler warning of an impending event called "The Convergence" that could collapse all realities into one.
As Livia’s power grows, she must confront her fragmented identities, uncover hidden truths, and embark on a perilous journey to find the Source of Infinity—the only hope to stabilize the multiverse. With time running out and the boundaries between realities weakening, Livia faces a race against the shadows that haunt her to prevent the collapse of all existence.
