book of the short sun

I there, just got introduced to the list, and have spent (rather too many) hours reading some of the archive... Some very enlightening discussions for sure.. Anyway, on to my point... Are the books of the short sun (on blue's waters, in green's jungle's, return to the whorl) open for discussion... If so I=92d like to start a discussion on (cross over) time lines, relativity, and travel both with regard to all the "sun" books I look forward to the ensuing chaos -Russ (and I aint manx)
