4. My favorite gem of character-naming advice was gleaned from experience: don’t give any of them names that end in “s.” Or if you do, don’t let them own anything because making s-characters possessive is a bear. It looks strange on the page and saying it aloud gives you a lisp. The only thing worse than ending a character’s name with s is ending a character’s name with two s’s (s-es?). In Five Days in May, my main character was Princess. And when I wrote about Princess’s successes, I thought I heard a Raven knocking, knocking at my chamber door—only this and nothing more.
