I should read more sci-fi/fantasy/something! I really enjoyed learning about this future Earth, a ‘utopia‘ where attachments to nations are discouraged, & serious relationships are outlawed until you‘re 35+ - an obvious problem if you‘re young & in love.
Unfortunately, I wasn‘t keen on the main storyline - a couple in space, 90 minutes of oxygen left, looking back. Neither the characters or writing grabbed me, but I enjoyed visiting their world.
