It was nonfiction! In fact, it was in that library 15 years ago, and I think they have a website... However, after a brief search it seems they have a lot of books on Cicero.

I was obsessed with Rome (thanks to my high school Latin class) and the name Cicero seemed so cool and elegant to me.

I remember I'd stay up all night reading it. But I was such an idiot. At the break of dawn, I'd throw seeds at passersby beneath the window (high window) and yell I AM ELZIO REX OF THE BRITTTOOOONNSSS until my sister yelled at me to stop.
