I think that I read that Shopaholic and Baby is the last book of the series. In that book the author pretty much wrapped everything up. We knew that Luke's business was doing better and that he closed down some offices in other parts of Europe. Becky also did a lot of growing up in this book especially. She seemed excited about being a mother and I got the impression that Luke would eventually buy them a house to live in. I also thought that Luke changed a lot in each book but changed the most in this book.
I didn't get that impression at all. I agree that it looks like Luke's business is getting better and such, but I didn't get the impression that this was the last book in the series. Sorry I thought you were talking about Mini Shopaholic. I hope that one isn't the last one. I still felt like things didn't all get wrapped up.
