Challenges from Exploding Steamboats discussion

In the original challenge, it was strongly implied that this should be via the on-site friends' recommendations feature. I think https://www.goodreads.com/recommendat... is a shortcut to this list. I've noticed this feature hasn't been pushed by the site as much as it was a few years ago, so if your list is kinda sparse, just pull something from your updates feed.

I am going to count Anxious People for this prompt, because several friends who are IRL and Goodreads have recommended it recently, albeit not through the site. I don't know if they know about the recommend site. I had forgotten about the recommend site and will play with it some more.
