Has the release date changed? because I can't find it on amazon anymore....

Hi Jenny. There was an issue with the pre-order and it got cancelled unfortunately (I have the worst possible luck setting up these things it seems).
The release date won’t be affected much however. I have republished it already, this time as a live release rather than a pre-order and normally those never take more than 72 hours to become available when they are novella-length :)
