Scythe/Thunderhead/The Toll.

The Illuminae Files trilogy is a really fun experience in audio format.

My go to suggestion would be the Scythe trilogy by Neal Shusterman, but I’ll suggest that to anyone who listens to me, 😅

If she likes historical fiction and YA, maybe Anatomy: A Love Story by Dana Schwartz.

Sticking with YA (because it’s what I know) — anything by Kara Thomas, since you said she likes thrillers. Riley Sager is good with thrillers, too.
