A problem with Luna's Direct3d 11 book is getting the samples to compile and run without a lot of problems. The book itself appears to be pretty good, but you'll have to create your own projects, perhaps copying code from the downloaded samples. I finally gave up since I couldn't get past the samples for Chapter 4 without spending an hour or more on each sample, searching for the reasons for compile/run errors, just, for instance, to display a static vertex shaded cube.
Note: some of the problems aren't (directly) Luna's fault. Microsoft made some (later) changes which screwed things up. E.g., Luna used VS2005 for the samples. Later versions of VS don't like his setup. Some of the fixes for problems are addressed in various places, but you'll have to spend some time searching around for those fixes. However, Luna's fault or not, having to create your own projects because Luna's won't compile/run is a pain and makes actually learning DX11 a side issue rather than the purpose of the exercise.
Also, getting help with his book/samples is problematic. The d3dcoder.net forums are pretty inactive and most of the posts are now spam (selling houses, kitchens, etc.) I'm not even sure there are any moderators for the forums anymore. It's a shame, 'cuz Luna's DX9 book(s) and samples are excellent.
