Dispatchers Vengeance of the Dark by Andrew Lamb
Supernatural thriller set in modern day London.
Marcus Townsend is a seemingly ordinary college student with an overactive imagination and a lack of drive. All that changes in one night when his parents are attacked and three brutal murders are committed in London by an assassin who defies the laws of physics. The only link between the victims is a strange red and black rose. Marcus must uncover the truth behind the victims if he is to evade their fate. But he soon learns that the stakes are far greater than just his life.
