(Long belated reply, sorry!) But yes! I nearly wonder if writing short vs writing long are different skillsets. I wonder this out loud because Mary Robinette Kowal wrote one of my favourite short stories not that long ago about an old woman getting the chance to space travel off Mars. It was phenomenal, and I was so excited to see she had a book coming out...and I didn't make it through all of the amazon sample, even. So while I knew intellectually (same way that 100m swimming sprints vs 10km swims are different trainable things) that they require different pacing and characterisation and etc, it's kinda neat to have to so tidily demonstrated, even if I couldn't put my finger on either of the poor showings except to vaguely say they were wooden and stilted? :)
