im on book 4 for the first time, which book shoujld i read next- Book 5 or 8?

I prefer to read books of a series in the order in which they are written.

My advice would certainly be between 4 and 5. I finished it myself last night, and while I echo the sentiment that for me it was like a reunion of good old friends, I'd have loved reading it in place. You'll see why when you read it.

I just finish book 4 last night and am facing the same dilemma... go right to book 5 or read TWTTK first. I'm leaning towards reading the series in the order it was published, but it seems like most here have said they think TWTTK is best read after book 4 instead of at the end of the series. I ordered both off of Amazon, so I'll have a few days to make a decision before they get here.
