The Floating Girl (Rei Shimura #4)

Rei Shimura is a Japanese-American antiques dealer who, looking to supplement her income, has begun writing a column for the Gaijin Times, Tokyo's English-language newspaper. When the paper's owner decides to transform the publication from a conventional news outlet to a comic book magazine, Shimura gets what is, for her, an unwanted assignment--to write an article on the history and culture of manga. Shimura discovers Mars Girl, a manga that follows the adventures of a superhero, and the Showa Story, in which the superhero travels back in time, to 1930s Japan. Determined to keep her job at the newspaper, Shimura pursues Mars Girl's creator, Kunio Takahashi, in both the hip and the less-than-savory sides of Tokyo.
