Of course I can stay with a subject that I am familiar with and authors that I had read but I often just want something different.
I check out the flap then just open a few places at random and read a couple of chapters.
If I see dialog I will read some to see how well it flows.
AT that point I either like their style or I don't.
These days I read mostly online and ebooks.
It is always hard to find English language books in foreign countries.
I speak Spanish so, so and reading Chinese is impossible so I really want to read in English when I am reading for pleasure.
