Once in a Lifetime originally appeared in the horror anthology All Dark Places, published by Dragon Soul Press. Papercut originally appeared in the romantic fantasy anthology First Love, published by Dragon Soul Press. Here are both stories, available for download.
As an added extra, if you’re interested, you can also check out the screenplay version of Papercut, which was submitted to the BBC Writers Room in January 2021. It made the top ten percent of five thousand odd submissions (but alas, didn’t progress to the final round).
