Yes, work on the book continues. I have been slowed by recent issues with family illnesses (my elderly mother), personal health problems, and laptop computer problems (keyboard + carbonated beverage = AAAGGGHHH!).
However, things are progressing thanks to help from my saintly spouse and dutiful offspring, all of whom took pity on me. Actually, they got tired of my whining, but it works out the same anyway.
Sometimes I feel like I am imitating that logic problem where you travel half the distance. Then half the distance again. Then half the distance again. But never quite make it all the way.
However, completion is at hand. Unless this new (old backup) laptop bites it also. Fingers crossed.
