Book 2, the sequel to Vampire's Key is developing well with rewrites and plot developments being ironed out.
I've just started a character rewrite addressing feedback from book 1 and following my gut. I think it will strengthen the second book.
The themes continue following Dominant Female Vampires and their naked male servers with sexual and blood rites and keyholding being consistent themes.
Hopefully I will have the first draft of book 2 completed by the end of 2020.
