I know that I'm an on-and-off reader, so I put down 12. Sometimes I'll blitz through a 1000 page book in a week, sometimes I'll not read for months.
I've got a StoryGraph account and have joined some reading challenges, but I don't think I'll be able to stick to them. I plan to read certain books, then I see something else and go "Oooh! Shiny!!" and then the planned reads are forgotten.
I have found that I like to have two books on the go so I can switch between the two depending on my mood. I did this with two fantasy/dragon genres, and I probably shouldn't do that again. I started mixing them up.
Ive just finished a book and about 2/3 of the way of another, so I'm looking for another to fill the gap. Just cracked Yellowface by Rebecca F Kuang, but it hasn't hooked me yet.
