I don’t so much mean something like reading a series from beginning to end, but, say, a string of books that all take place in Paris. Or that have anthropologists as the main character. Or were written in the same year. Something like that… Something that strings them together in your head, and yet, otherwise could be different genres, different authors…
On first impulse i want to say no. I want to say that i do read series but not necessarily books in groups like this question describes. I know i get on kicks where i read a bunch of fantasy, a bunch of popular science, a bunch of historical fiction, a bunch of horror, a bunch of philosophy. And really, looking at my blog since february seems to have shown this. I feel like when i just glance what i've read it's random except for some of my challenge books. But then when i really reread some of the posts i do realize that there is a method to my madness. I might have pulled a book out of my lists to read next but looking back i can see why i picked that one. Sometimes reading one book does point me directly to another; in science or philosophy specifically i'll decide to read another book that the first references. As i just finished up the Philippa Gregory novel so i was looking at some Tudor England history stuff but hadn't picked one to read yet. But the reason i picked up the Gregory book was because i really liked Poison Study.
So that is a long way of saying, yeah, i do have my own twisted logic sometimes in what i read.
