I would consider Touch by Claire North a thriller. It may be more science fiction than fantasy. There's probably a number of science fiction books that fit this (like Ready Player One and Lives of Tao) . And probably some urban fantasies (perhaps books like the Miriam Black books and definitely Myke Cole's books. Even Sanderson's Steelheart).
I know some of these are ones we've read. But its easier to think of examples off the top of my head using books I have read.
