Guessing time...
Author 5 = KenJ
Author 11 = Lynn
Author 9 = ...Millefeuilles?
I'm not brave enough to keep guessing. These are too vague! When you're coming up with your own clues you think you're being clever, but then reading them in a list I'm like geesh, I can't even place my own sometimes.
Def wanna know who author 7 is... and if they can tell me how to incorporate said martial arts skills into scenes more fluidly... nudge
