This is a very thoughtful tale, told from the POV of a high-functioning austistic man in the near future. The SF elements are understated, making this more deserving of the (overused) label "speculative fiction." It explores issues of identity and disability and what makes you you
, as Lou Arrendale wrestles with all these issues when given the opportunity to accept an experimental treatment that will, supposedly, cure him of his autism.
That said, there were long stretches of the book that were just Lou going about his day to day life so we can see how he, as an autistic person, thinks and lives. The plot is fairly slow-paced and never really rises to a boil.
Very much worth reading for its portrayal of autism and the way it makes you think about disabilities (and what is a "disability"?).
