Mastering Windows 8 C++ App development is a good read I did enjoy it.
It has a good introduction to the tools needed for Win8 Development and WinRT it covers in detail the project structures, which is always something that is lacking in these kind of books.
Covers how C++ has evolved with a brief section on the newer features of C++ 11 like nullptrs, Lambdas, auto and smart pointers .
It covers building a UI using XAML in great detail, so when you finish you should be able to build a UI of your own.
Most developers would dissect API them selves and learn that way but this is a good book to supplement the knowledge gained by working with the API.
This is a great book for C++ developers with no previous knowledge of Windows Store apps and the Windows 8 world. It can be read not only "from begin to end", but also you can jump directly into the Sections/Chapters you find more interesting. I personally enjoyed the details of the "new features in C++11" section (described in Chapter 2) and the way the MVVM pattern is introduced (Chapter 5). A "must-have".
