Question about Swordheart (T.Kingfisher)

So I'm reading the Sunday paper, as I often do on Sundays, and I see that the ABA bestseller list has Swordheart (T.Kingfisher) listed 6th in the fiction category.[1]
But I'm curious. I did indeed enjoy the book, but it was written in 2018. Per isfdb[2], there was indeed a new edition released a few weeks ago.[3]
Does anyone know what's causing the sudden interest and resurgence in sales? Movie? Something else? I've searched some, and I didn't find any special news or anything.
Just curious,
Tony
[1] Yay Ursula!
[2] Yay Ahaseurus!
[3] Yay Ursula again!
