I really enjoyed my time listening to the stress simulator 3000. My favourite bit was how the entire book was written like the most aggravating parts of Jurassic Park where Lex is yelling at Timmy to DO SOMETHING and Timmy shouts back IM TRYING. I really did like the twist in the very last line though.
I don't know Airframe
I definitely wouldn't listen to The Sphere, it is very stressful and repetitive and I found myself begging them to get to the point, and the characters are so stupid
I can't imagine it would be more enjoyable to read, there are some good ideas but it just fails to hit them in a good rhythm.
