This is God’s work. Or at the very least, the work of a Grand Maester. Joeltronics made this very useful graph that shows which episode of Game of Thrones the TV show corresponds to which chapter and which book in the A Song of Ice and Fire books (aka the Game of Thrones books). That way you know what’s been shown when and what’s been omitted in the story.
If you were a book reader originally, you see what the TV show misses. If you were a TV show watcher first, you get to see where the series stands in relation to the books. If you’re neither, well what’s wrong with you.
You can also check out the more interactive version of the graph here.

You can find a chronological version of the graph below (A Feast for Crows and A Dance with Dragons, book 4 and 5 in the series happen in the same timeframe with different characters in each book):
