Of partial importance to the storyline is Tolstoy's novella [b:The Kreutzer Sonata|141077|The Kreutzer Sonata |Leo Tolstoy|http://d202m5krfqbpi5.cloudfront.net/books/1320503925s/141077.jpg|2266654] (which I read immediately after finishing Second Person Singular). Kashua masterfully worked in many of Tolstoy's themes & ideas (jealousy, relationships between the sexes, the influence of art in life & passion, etc...), paralleling these ideas in his story -- similar themes, just set in a more modern time & with differing religious beliefs from Tolstoy's.
Overall, a beautifully done work that muses on the nature of identity, our ability or inability to change identity, & the impact of emotion/art/beauty/self to impact our lives.
