The one I have checked out is v2 by Hickman, Prime Elements. Scanning thru it I remember reading it before (it’s where your blog name comes from, but also it has really weird looking horse-head aliens which I can never forget so I know for a fact I read it). I think the next one is Unified Field Theory but the internet was really confusing about this. The conflicting info I managed to figure out was: The Future Foundation series is about to start and ‘Unified Field Theory’ may or may not be part of that series instead of F4, and if it is part of F4 then it’s v3 or v4, or it could be v3 or v4 of Future Foundation. Checking what issues are collected in it did also gave me conflicting info and the Wikipedia page doesn’t have the trade’s names (just lists them as ‘F4 by Hickman’ with the volume and issues collected)
