Actually the last "book" I read wasn't a book at all, but issue 1 of Galaxy. I read that for many years while it was still being published. I am a HUGE Science Fiction fan and remember a large chunk of these stories. If you like science fiction all Galaxy and all If issues are online (read in PDF form) and/or downloadable for free from the Archives. I can't recommend this place enough y'all! https://archive.org/details/galaxymagazine https://archive.org/details/ifmagazine Worth looking at for the great reading alone, but you gotta check out those old timey covers!
Some great reading in those issues. But the covers are interesting indeed. Watch their evolution over the years.... "themes" .... etc.
Currently reading The Loneliest Girl in the Universe by Lauren James. It is a young adult book and about a teenage girl born in space and it the only person left alive on the space ship after her parents pass away. Enjoying the story so far.
I guess the last few books I've read were : The Hobbit - J.R.R. Tolkien Murder on the Orient Express - Agatha Christie And a Biography of Dwight David Eisenhower's White House years.
