I just wanted to thank "Bill", for his e-mail (as he came across as anonymous, so I could not respond). I agree that Beth is a more interesting character than Josh in many ways, but Josh continues to be Beth's conscience in helping her determine how she deals with her power and a certain level of newfound freedom (though she still is technically Josh's).
I'm not sure if the story will go into a fourth installment, but if it did, you would probably see Josh and Beth start some kind of business that utilizes the skills and abilities of his wives (no, not a brothel as some might suggest, lol).
As I've mentioned in previous blog entries, it is quite likely that there will be a third installment. Barring a worsening of my health issues (which do hinder me from doing a lot of writing), I think it is likely that it will be finished before the end of the year (as it has been partially written and mapped out well before the original story was first published in 2010).
Again, thanks for your interest (and to everybody else who has enjoyed the story too)!
