“Well, Foxx was my grandfather’s name—but it only had one x at the end. I wanted to name my first little boy that since I was a little girl, and luckily, Kixx agreed. And because his mother put two x’s at the end for reasons I’ll never know, we put two at the end of Foxx’s.”
I should have noted this in my review of Fluke, but Kixx was only spelled Kix in the first two books Flirt and Fling.
