I suspect it's another variation on the following plagiarizers, many of whom have been taken down from Amazon. Presumably because they were identified as plagiarizers:
Blake Barkley
Gabriel Garnier
Leah Larkin
Leigh Temple
Millie Carter
Scarlett Johnson
With the exception of Gabriel Garnier, they all used a similar cover style, as exemplified with the stories you posted. When I see that, I check to see if I can find the original source using the google search trick you ( at least I think it was you) posted.
Attached is a list I posted at 8Muses that identifies the source of the story that was ripped off for many of the authors above.
