Thanks for taking over the cover, Kylie. I'll make sure it gets cocredit.
Two things I just thought of that we may need to add:
1. "A collection of short erotic fiction to support Australian bushfire services" (okay, that's kind of crap; if you can word it better, by all means please do, otherwise just jettison the subtitle)
2. "Collected by Army of One"
And I can't remember if the book title has an 's' or not, but if it does, I can easily drop it; looks better without it, plus works as a double entendre.
