I replied below with an exhaustive list, but if I had to recommend one book it would be Firekeeper's Daughter by Angeline Bouey. It's a really good thriller.

My average book length was like 340 pages, so that would be like 4-5 days of reading 30 mins before bed. Part of my routine is no phone before I go to sleep, so I spend my last hour before bed reading and journaling.

I also listen to loads of audiobooks when I'm walking or riding or driving.
