In The Prince of Tides, Tom Wingo meets with Dr. Susan Lowenstein, a psychiatrist, in the hopes that together they will be able to help Tom's sister Savannah, who is suicidal. During his meetings with Dr. Lowenstein, Tom reveals his and Savannah's troubled childhood, which included poverty and abuse. In the end, these sessions not only end up being the key to helping Savannah, but also Tom, as he and Dr. Lowenstein work to heal old wounds and help Tom move forward towards forgiveness and a better way to live.
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.
