The novel Time's Arrow tells the life story of a Nazi doctor, Tod Friendly, in reverse. It is narrated not by Friendly himself but by a presence who exists within the doctor but has no connection to his thoughts or actions. The reverse timeline of the story seeks to make sense of the horrors of the Holocaust, particularly the main character's involvement in them. Since things move backwards, the novel doesn't show the doctor as he progresses towards evil, but rather as he progresses back to a life of innocence.
Boasting the largest collection of book summaries, BookRags is the best option for titles you can't find elsewhere. They offer all of the basics (quotes, chapter summary, characters, historical context, literary criticism) but also walk through a few major topics that recur throughout the book, which can be particularly useful for essay writing.
