I've been a bit out of the loop with Austrian Economics (last re-read of Human Action was ~15 years ago). I'm very well read in it and enjoy the aesthetics of the theories and the history of thought books but got very tired of the online flame-wars and the political side in general (both the pro- and anti-Austrians). So Praxeology of Privacy sounds like an interesting read, I'll give it a go this year.
