To get you started on this question, let's brainstorm some reasons why people might want to read The Ruined City by John Wilson. First, the story has an interesting and exciting plot. The protagonist, Howard, is just a normal tenth-grader, but he is soon caught up in a world he has never dreamed of. When Howard meets Cate and discovers that he is an Adept, someone who can communicate with other dimensions, he ends up embarking on an exciting journey through both time and space to try to save our world from a world filled with monsters that is fast approaching Earth.
Further, the novel's characters are well developed and easy to relate to. Howard is a normal kid, and he has all kinds of problems, including odd parents, a failure to be popular, and scary dreams (that just might be real). Cate is a rather strange young woman, but she draws Howard into a new view of the world and of himself. Many readers might wish they could meet someone like Cate who could teach them new things about themselves and reveal to them how special and unique they are.
Also, the novel is well written and contains some fascinating motifs. The golden mask, for instance, is deeply symbolic. Howard and Cate are part of an elite group of people with supernatural powers. Our world proves to be only one of many worlds and dimensions that sometimes collide and that people like Howard and Cate can visit in dreams. The author weaves both popular culture and a rich mythology through the plot. All of these combine to stimulate the imagination and hold readers' interest.
