Not everyone lived to see what the world would become. Those who were incinerated by the blast were atomized. Their souls were left wandering the cracked remains of the Earth with nowhere to go. They are known to humans as Shadow Walkers. Fed up with the confines of her comfortable world and her constricting grandparents, Princess Victoria Harlowe hatches a plan to escape the only home she has ever known, bringing along a lowly Will Norwood, a Paladin-a soldier in charge of the protection of the castle walls. Together, the disparate pair navigate and explore the ruinous and desolate world, kindling an unlikely friendship as they uncover truths that shake the shattered Kingdom to its foundations.
