   Summary

   Like so many things, it had seemed like a good idea at the time. When Aventurine was invited to teach a class for Paperfold University, he had let himself be intrigued, even a little flattered. The self-made Avgin without any formal education, invited to speak to a classroom full of impressionable young Fortune Academy students.

   But what he hadn't counted on was his TA. Fortune Academy's top student had been assigned to be his assistant for the semester, helping him grade essays and passing out papers in class. Sunday Oak did all this and more without complaint, a polite but indifferent expression on his stupidly handsome face.
