Is one a sequel?

Commas are fine, but semicolons have their place, too. Here, that place is after Anabel, High, and Everywhere. Because there aren't novels called "Women" in this list. (Or one called "Women" and one called "Women, Everywhere", either.)

"It was during the 1920s that Gene Markey first became a writer, specializing in novels about the Jazz Age. Among his titles were Anabel, Stepping High, Women, Women, Everywhere, and His Majesty's Pyjamas."

(This is from Wikipedia, but I edited it to add the semicolons, so (hopefully) it's not the same now.)
