Ascension by Nicholas Binge and The Frugal Wizards Guide by Brandon Sanderson.
Ascension is not only a bad book, it’s extremely stupid. Like proper dumb. So much here that doesn’t really makes sense, or is just flat out stupid. The dumbest plot twist I have ever seen.
The other book was just a big miss. It missed everything it tried. Felt like an expanded reddit story.
I feel his point was more that people use the term too lightly, most people self diagnose with aphantasia, just because they have poor imagination. But i might be wrong
