That is quite the well-assembled list. All of the context is helpful for everyone to make suggestions. Also, your comment about Greg Egan is pure awesome.
Gareth L. Powell's "Embers of War" series was excellent. Scalzi's "Starter Villain" had me laughing painfully hard at points.
I went to a state school in the early 90s. Taking a specific sequence of physics classes was the cue for Navy nuke tech recruiters. And they were aggressive. Turns out someone in the registrar's office would search for students with that class sequence and sell the info to Navy recruiters. The person got fired, and there was a bunch of pearl-clutching. And yet military recruiters are still such a fixture of college campuses.
