His Robot Wife was written for entirely different reasons than any other book I’ve written. All the other books (with maybe the exception of His Robot Girlfriend) were written because I thought I had a great story to tell and I wanted to tell it. You could say that I wrote His Robot Wife for money, though that’s not entirely accurate. I priced it an 99 cents even though I could have made more by pricing it higher. I wrote it because I knew it would sell.
I publish His Robot Girlfriend in 2008, and it has been downloaded hundreds of thousands of times. Many people wrote and asked for a sequel. This was a big deal for me. But I didn’t have a story. As far as I was concerned, the story of Mike and Patience was over. Still, people kept asking. It took me three years to come up with a story for them, and I think it’s probably my weakest plot (but HRG wasn’t popular for its plot, but rather its characters anyway). So in 2011 I wrote His Robot Wife. It is short, at 28,000 words, but it went easily enough, and as it turned out, it has sold more copies than all my other books put together.
