"I was wondering if you and/or the blog readers have an answer for this: when you finish reading a book you really like, how long do you wait until starting the next book? Immediately? The next day? If it's one of a series are you more likely to go on to the next in the series right away or read something else first?"
For my part, I always start another book immediately or that same day at least.
But never another book by the same author and usually a different kind of book. For instance the last few books I've read: BROKEN SHORE (crime) STRANGLEHOLD (crime), FATHER OF THE RAIN (lit), I'D KNOW YOU ANYWHERE (crime), CARETAKER OF LORNE FIELD (horror), THE HELP (mainstream). Forgive the "dreaded" classifications here but I am trying to point out there are different sorts of books-mostly but not entirely about crime.
And also for this handful of books I finished, there are double the number of books I started and discarded over this period.
Years ago, I plowed right through any series I stumbled on but no longer.
What is your progression and what is the timeline. Does anyone wait several days to absorb a book before starting another one? Is your next book at elbow length?
