There are four books in the "You" series by Caroline Kepnes:
- You (2014) – The first book, which closely follows the plot of season one of the TV series.
- Hidden Bodies (2016) – The second book, which loosely inspired season two of the show.
- You Love Me (2021) – The third book, with a storyline quite different from the TV series.
- For You and Only You (2023) – The fourth and latest book, not directly tied to the TV series plot but shares the theme of Joe starting over in a new place
The TV series adapts elements from all these books but diverges in some significant ways, especially in later seasons.
