How do the episodes of Game of Thrones correspond to books wriiten?

"Game of Thrones" is based on George R.R. Martin's series "A Song of Ice and Fire." The first season closely follows the plot of the first book, "A Game of Thrones," but as the series progresses, it diverges more significantly from the source material, particularly in later seasons. While some episodes adapt events from the books, others introduce new plotlines or alter character arcs, especially after the show surpassed the published novels. The final seasons were developed with input from Martin but lacked the detailed narrative foundation of the upcoming books.
