Thrilling, yes. 
 High quality of writing, not so much. 
 The premise is not very original and there is way too much swearing for my taste. I do not think that you should choose this book if you are looking for a literary work of art, or a contemplation about society, human nature, art, life or any deep rooted meaning for that matter. However, if you are after a holiday or wet-Sunday book to pass the time it is certainly engaging. 
 I say well done for a first attempt of a self-published author.
