I have enjoyed reading the first of Jack Nightingale but it may because I quite like all things ''New Age''. It is not normally the kind of books I would read but I got into it fairly quickly. But for me, the real story is not the supernatural side, that was a bit spooky at times, it is the story of Jack Nightingale. One day, Jack learns that the life he knew, the parents he knew, his past was a lie. He was adopted at birth and was never told until he finds himself the sole beneficiary of his biological father. A father he never knew about, a father who sold his unborn child's soul to a devil in order to gain riches and ladies. And that was Jack's tragedy.
If you do not believe in the supernatural, or even acknowledge it, then I can understand that this book is not a good read for some and can seem over the top.
But if you do believe there is something somewhere, and you have an open mind, and you put yourself in Jack's shoes, then it is an enjoyable read. Do not dwell too much on the supernatural but dwell on how Jack is angry about his biological father and also about the people he still call his parents, his real parents but who lied to him by omission. It is a confusing state of mind.
