Tashi creates a virtual reality world in an attempt to recreate a thin place that serves as a portal between Earth, where she lives, and Ka, a world in another dimension where her boyfriend Michael has disappeared. Thin places, where the boundaries of two worlds meet, existed as folktales in Tashi's mind. That was before Michael used a thin place to disappear into Ka, a world in another dimension, leaving Tashi bereft and severing the psychic ties that knit Tashi to Michael and her three friends, who stopped talking to her the day after Michael disappeared. Convinced that Michael has left behind clues leading to him, Tashi recreates Michael's memories of his experiences in Ka into Ka World, a virtual reality world, in an attempt to simulate "The Dissolving," a brain state of information overload where notions of time and selfhood cease to exist, to create a thin place that can open a portal into another dimension to reach Michael. As Tashi follows the clues that Michael leaves behind on Earth, she unravels the tangled yarn of her broken friendships and confronts the risk of unleashing the dark side of immersive virtual reality experiences that threaten to rip apart the fabric of reality itself. A novel that explores love, loneliness, and transcendentalism, All The Thin Places asks the question, what is the nature of reality when the boundaries between the real and virtual worlds blur?
