Nocturne is “a haunting story of forbidden love”. It says so right on the cover. The entire story takes place in just a few days, which is more than enough time for the main characters to fall madly in love with each other.
Michael is a vampire (and Nicole is not). Michael’s secret is revealed to the reader early on in the story. Nicole misses every clue until something bloody obvious finally opens her eyes.
Can a relationship between a human, and a vampire, work out? This is the question that Nicole and Michael must find an answer to.
