Please summarize Moby-Dick for my upcoming book report.
Moby-Dick is a novel by Herman Melville that tells the story of Captain Ahab, who pursues an obsession with revenge against a whale named Moby Dick. The novel takes place during the 19th century and explores themes such as man versus nature, the quest for power and knowledge, and the relationship between men and women.

One of the most famous sections in the novel deals with Ahab's pursuit of Moby Dick and his eventual encounter with him. The chase through various seascapes provides the reader with a sense of wonder at the vastness of the ocean and the power of nature. Throughout the narrative, Ahab demonstrates his obsession with revenge and becomes increasingly deranged due to it. He eventually captures Moby Dick and kills him out of spite rather than justice; this section is known as "The Whale Scene." 

In addition to being about revenge and the search for power, Moby Dick also explores questions of morality and ethics. Ahab makes many questionable decisions throughout the course of the tale, often acting without consideration for consequences or other people's feelings. This mirrors the theme of hubris, which runs throughout the text: characters make foolish decisions based on their own inflated view of themselves, ultimately leading to disaster.

Overall, Moby-Dick is a challenging read but offers rich rewards for those seeking depth and meaning in literature. It challenges readers to consider complex ethical issues and grapples with the concepts of revenge and redemption. While it can be difficult, the payoff is worth the effort.
