I recently read via Libby a number of enjoyable SF novels. I started with one of my favorites, Iain M. Banks.
After I'd read a few of those I started getting recommendations from Libby, finally trying one that received my five-star award:
This is the story of an alternate history 2005-2010, where the big story wasn't the Iraq War, but a Wikileaks type character (the father of the protagonist of the story, Cora) who outs George W. Bush for lying about Aliens Among Us. ... that's enough without getting into spoiler territory. I found this one deeply satisfying!
Lindsay Ellis is also a YouTube personality
....where I found my next recommendation:
This is another alien story with a quite different vibration. A quick synopsis: A huge statue appears in the middle of the night in New York City, and aspiring YouTubers take video of it and are the first to be on this story ... identical statues have appeared in cities all over the world.
Complications ensue ... I still quite enjoyed this one ... four stars.
Hank Green turns out to be the younger brother of John Green, Hank and John are together the Vlog Brothers, who have an enjoyable YouTube channel with posts of generally about 4 minutes:
