As noted by fans on Reddit, there are plenty of differences between the source material and what ends up onscreen in “You,” but the core story arcs have remained relatively faithful. Since Season 1, which premiered on Lifetime, was based on the first book by Caroline Kepnes, “You,” while Seasons 2 and 3, which moved to Netflix, covered the second, “Hidden Bodies,” it is a reasonable assumption that Season 4 will dive into the third novel, “You Love Me.”
Without revealing too much of what might be coming in Season 3, if Season 4 utilizes the storyline introduced in “You Love Me,” the show will see another location shift. As described by Penguin Random House, Joe will move from Los Angeles to the Pacific Northwest, trading the urban environments of the earlier seasons for a job at a library in a sleepy island town.
Netflix’s confidence in the strength of Season 4 might even be based on the sales of “You Love Me.” The third novel in the series quickly made it on The New York Times fiction bestsellers list after being published in April 2021. The TV adaptation has enjoyed strong critical acclaim, and currently holds a 90% on Rotten Tomatoes. Hopefully, fans and critics find just as much to love abut “You” in the upcoming Season 3 and eventual Season 4.
