I only get about 30 minutes (my luch break) a day to read, unless I read at home too after work. I read Harry Potter 4 in about 3 months like this! LOL I got frustrated and just finished it in a couple of days in the end, cause I was enjoying it too much and I didn't like it being strung along for such a long time.
So yes I'll buy the next one after the rush! I think it's worth waiting for and reading at my leisure.
SAF - I would have said you can take as long as you like to read them (within reason).
