This book is the beginning of the saga. I recommend reading it in order to get to know the background of many of the major characters who will recurrence through out the series.
Ana BuFaye definitely believes in things that go bump in the night. Unholy Pursuit:The Devil on My Trail is futuristic, paranormal, romance story that also contains elements of sci-fi, horror, common sense, and philosophy. It’s a novel about the eternal battle of good versus evil set 500 years in the future that features saints, immortals, demons, and spirits. A recently single mother with a supernatural past suddenly finds her life in turmoil. Energy and a fighting attitude are her two best friends as she is always on the road fleeing malevolent forces coming after her. She gives as good as she gets and always manages to stay one step ahead of her pursuers due to her inner qualities and otherworldly assistance. She is more than just a tough, strong woman fighting to save her family: she is a warrior called to battle to fight for the greater good.
Unbeknownst to her, the one in whose arms she sought love and comfort in is actually an immortal, who according to ancient texts and tomes, myths, and legends is far worse than Lucifer. Her new love is the former king of hell, Azazel.
