How to Live Safely in a Science Fictional Universe

This book caught me off guard a little bit. I expected mindless fun, action: a filler. But instead, it was a very human story which happens to be set in a science fictional universe. While the plot does lean heavily into time travel, which is the obsession of the main character's father, the centrepiece is not the time travel itself but the emotional journey of a man raised by a parent who sacrificed everything to his work. Also currently reading GEB and found the self referential nature of several elements of the book interesting. All in all a weird but welcome detour into unhappy man themed sci fi.
