Pretty much all of Diane Duane's Wizards books. It's pretty literal in High Wizardry where Dairine and the entity that becomes Spot redesign a solar system by rewriting how it is described. But the idea is there in all of 'em. While I'm not sure the author intends it that way, I read Juanita and Dairine's mom as Hispanic (partly so Nita's name makes sense, and partly because otherwise she doesn't make much sense as an east coast Catholic mommy), and their dad as distantly Irish-Catholic, like Irish Potato Famine vintage for immigration. This has the nice side effect of making Aunt Annie's Irish immigration make a little more sense.
