Walker is an ordinary boy from the outer world, in other words, our world. He was born with a strange star mark on his cheek. At first he didn't like it, but then a boy from the underworld comes to tell him that the star might just be the marking of a king. The boy takes him to a place in the underworld called Nebula where people need no food or water. They have a ball of light called "the source" and every living thing glows. Before Walker can decide if he wants to be king or not an old enemy of Nebula - The Back Count - attacks! What should Walker do? Should he stay and defend the kingdom or should he retreat to his own world? Warriors of the Black Shroud kept me turning the pages, but I didn't feel any emotions about what happened.
