I would recommend checking out audio books as a medium for reading. It allows you to increase the speed to whatever works for you, so 2x for me, and listen to a lot more in a day. It also frees you to listen at any times you have nothing cognitive happening, so dishes, washing, cleaning, etc.
As for single day books, the first book of the Bobiverse series by Dennis E Taylor. I loved the whole series including the recently released 5th book and the first is only 9.5 hours at normal speed, so about 4.75 at double speed.
Also All Systems Red is the first book in the Murderbot series by Martha Wells. The perspective of a SecUnit, a type of sentient cyborg, which has hacked its own programming and removed its limiters so it can act freely. This means no guard rails, no rules, no limits, which results in lots of TV shows being watched and avoiding humans. It is snarky, fun, and interesting. It comes in at 3.5 hours normal time, so 1.75 at double speed.
