I am working on the information for a fantasy novel I wish to begin soon, and I'm struggling with one part of my plot... The plot is... This story is about a forbidden love interest between a human and a vampire. The story begins inside a castle of vampires - in a training arena. The female vampire - who is a highly trained and dangerous assassin - is to be paired with a human sent to be trained into warrior. The question is, how can an assassin train a soon to be warrior, especially human? The "bolded" section is my concern... is it possible for a female vampire assassin to train a male human into becoming a warrior?
