Mason & Dixon might be Thomas Pynchon’s most human book.Its main characters are richly drawn, and they center the narrative.Yet the novel is also packed with historical allusions and an eighteenth-century vernacular that some readers may find difficult to navigate.A "Mason & Dixon" Companion offers this navigation line by line, unpacking Pynchon’s puns, his many references, and his pet themes.Brett Biebel provides a contextual map, episode-by-episode summaries, and page-by-page annotations explaining allusions, defining obscure vocabulary, and illuminating the book’s major themes.The goal is to help readers work their way through a difficult yet remarkably rewarding novel from one of American literature’s most significant writers.In a voice that’s both relaxed and informed, the Companion illuminates what Harold Bloom called “Pynchon’s late masterpiece.” It crystallizes the prescience of Mason & Dixon, situating the novel within Pynchon’s broader oeuvre, while being fun to read in its own right.
