This is unfortunate, because I was really looking forward to this book (as well as "Land of Lisp"; c'mon Barski!), but there's not much you can do when it is stopped for "health reasons". The vagueness implying that it is probably fairly bad. All that can be done is to wish him well and hope that he recovers from whatever it is that he has (if it is possible).
Land of Lisp is looming, don't worry!
(I'm editing the book, by the way.)
That's great to hear! Thanks for the update (if a bit of a strange venue.) :)
I hope he gets better. I still use his P4 COM plugin for LispWorks.
"Abandon" is not the right word, because it usually implies moral failure or, at the least, defection. In this case, he's taking a break for health reasons, which is an entirely different situation.
I hope he gets better soon.
To be fair, "abandon" is the word he actually used in the OP.
