New book, maybe?

I've been thinking about writing a new book, this time for people who would like to learn C++ from the beginning. I'm still not sure about going forward with it, and about the details, but it will, without a doubt, already be up to date with the latest revision of C++. My previous book, about good programming practices for C++, has already seen some sales, although not really significant. I'm still unsure if I'm going to merge the subjects of both books or keep them in separate volumes. It will, however, take much more time to release than the first one.
