There are actually three Rhondas (that I know of) wandering the fictive literary galaxy and all three can actually be found in one book: Joshua Mohr's debut novel, Some Things That Meant the World to Me. There is little-boy Rhonda, old-lady Rhonda, and Rhonda (a 30-year old man).
As Donald Ray Pollock mentioned in his blurb for the book, "[Rhonda] is one of the most troubled and heartbreaking people you will ever encounter in literature." Though which Rhonda in particular he refers to is uncertain. Read the book and find out.
The author got the name tattooed on his arm.
