Give her the Asimov Foundation series. She may really dig it once she gets through Asimov's writing style, which is a little more dense and opaque than a modern sci-fi author's. But it's filled corner to corner with mid-20th century version of high sci-fi (aka the future tech in the book, may seem a bit anachronistic and/or quaint to a GenZ sensibility).
Others - World War Z (Max Brooks), Station Eleven (Emily St. John Mandel),
The Bobiverse series (Taylor) and 2030 (Albert Brooks)
I think she'd likely love the Bobiverse series. All three of my boys (and me) read the series this summer and really enjoyed it. It all about Von Neumann probes, settling Earth-class planets in nearby star systems, interstellar war with human proxies and alien civilizations, abandoning a dying Earth, and a really well executed level of snark and goofiness.
