They are a complete kick to read. I first read them a good 40+ yrs ago and loved them. I got the set in ebooks, I think I have them all now from Baen. I intended to read them a couple months ago but life got in the way of everything.
Just always remember this "...grumble you may, but go you must..." Read that as a kid and for some reason it still will flip a switch in me when I am just not wanting to get something done...
Have a BALL reading them...
