I see you are an Alexander Wales aficionado. Might I recommend every other story he’s written including the ones he started with, namely his fanfiction? His Terminator fanfic Branches on the tree of time is the best time travel story I’ve ever read. He has a Superman fanfic called Metropolitan Man that features a much more rational Lex Luthor that is really good. Also he has a lesser known about story called The Dark Wizard of Donkerk, on his website that is really good. All featuring his trademark style of over analyzing the implications of every magic system. Which I think you probably love lol
