The Cider House Rules is the story of Homer Wells, an orphan who apprentices as a doctor to his orphanage's resident physician, Wilbur Larch. Larch trains Wells to perform abortions, an illegal operation at the time. Conflicted, Homer leaves and takes work at a cider house where he works as a hired hand before realizing after Larch's death that his mentor did good and necessary work for women who could not help themselves. Wells takes Larch's position and becomes the orphanage physician.
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.
Their book summaries aren't as good as other providers, but PinkMonkey often has interesting insights that aren't mentioned elsewhere on the Internet. For example, they go over literary elements (like setting, conflict, and mood), compare and contrast, and symbolism/motifs. It's a good site if you want to find a unique fact or angle that other students don't know about.
Includes the standard sections found in most book notes, including a book synopsis, chapter by chapter analysis, author biography, character list, essay topics, book report ideas, and study questions. This website is less comprehensive than other book notes sites, but could be useful if you're looking for a quick review.
