I'll read Vince Flynn, Clancy (well up until he got divorced), Konkoly, Le Carre, Silva, James Corey, Mather so spy or sci-fi. I read most sci-fi / fantasy big names when I was a teenager. Wife will read murder mysteries, Janet Evanovich, and such. She is pretty much done with mysteries and getting repetitive for her just like TV cop shows.
Where we both enjoyed was Harry Potter series. Another one was Finding Home series by A. American. That one is basically prepper fiction which I liked for the ingenuity of surviving as well as the story. Wife liked it for the same reason she likes Walking Dead, surviving and how people interact in the face of disaster and survival. As she tells me, "The Walking Dead is not about the zombies!" Of course I watch one show and it was all about the zombies.
