Austrian welfare economics

Does anyone have any good sources in regards to Austrian school perspective on welfare economics? My current text for my public policy finance econ class is using Johnathan Gruber's (obamacare architect himself) text and I just keep having a lot of problems with the conclusions logically following the premise. I looking for stuff in regards to externalities (positive and negative) and market failure. I mostly want the Austrian counter argument to mainstream welfare economics. I know this sounds really muddled but anyone out there kind of understand what I am getting at?
