I just got this book the other day and am super excited about it. When most of my casting was pretty straightforward - it was easy! I went years and never had a casting not turn out. However, as I've progressed and started experimenting - I try risky things that I haven't done before and often come up a little short. There is a great troubleshooting section which is just what I need! Its not a huge book, only 116 pages, but I can tell it is going to be a fabulous resource. It has a lot of info other books I have don't cover and one aspect I particularly like is that it is a collection of articles from different authors. You can check it out on Amazon, or the next time you place your Rio Grande order, they have it too.
