Well, there is.
"In the Marrow" is a sequel, of sorts.
Last summer, I wrote another story with Zakiya and Jae Lyn de la Rosa, titled "Better Than Everything". It was published by SQ Mag, an online Australian zine.
Unlike "In the Marrow", "Better Than Everything" is a longer short story, and goes into more detail about the relationship between Zakiya and Jae Lyn.
Give it a read and let me know what you think.
I think you'll enjoy it all the same.
