Booking through rolls

"Do you get on a roll when you read, so that one book leads to the next, which leads to the next, and so on and so on?"

At any given time, I am reading three books. They are as diverse as can be. However, after reading Book 4 of Harry Potter series, I did go on a roll, reading Book 3, 2 and 1, in that order! After that I read it in the serial of 5, 6 and 7. I tend to read travelogues one after the other. I suppose you can call that being on a roll. I once read three books, about Afghanistan within a span of ten days. In my younger days, I read Agatha Christies for a whole month. I have never been tempted to read a whole series at one go. I can just about start reading any.

Now I try to be more selective. I prefer my next book to be as different as it can be. Although, recently I read five Jodi Picoults one after the other. Still those were very different from each other.

Nonetheless, reading challenges are most of the times, themed. Hence one tends to read books having a few or some common threads. I wouldn't call them similar though.
