Y: The Last Man - The Deluxe Edition Book One

I honestly can't remember how far I got in this series the first time I tried it, for all I know, it wasn't a heavy course load or a sucky mid-twenties job that stopped me finishing it (as it stopped me reading most things for about a decade), it was that the publication run hadn't yet finished. This time I checked series completion status before I started! And after this volume, I'm very interested in reading on. 
What I'm now used to from Brian K. Vaughan (Saga, Paper Girls) holds: the content is not for kiddies, but the banter is en pointe. 
Fascinating exploration of the possible changes - not only in a female only/female led modern society (not to erase historical matriarchies/female politicians or Queen-fronted monarchies) but also a post-apocalyptic society, where near half it's population disappeared and all the existing geopolitical structures are struggling to get back on their feet. Let the chaos continue! On top of which is the mystery of what happened to kill almost all that men...hold placed on next book!

⚠️Bodily fluids bonanza, mentions of SA, self-mutilation, pretty consistent bloody violence but not heavy on the gore
