For lovers of passion, drama and especially the morbid I recommend this novel which was written by Megan Maxwell a Spanish writer who undoubtedly put her imagination to fly with these books.
It is a behind for adults since it is not advisable to leave this kind of writing within the reach of minors for its explicit content. If you are what you are excited about reading that is both entertaining and morbid, you should read these books, they are dynamite for the neurons and the imagination without mentioning that I have asked several acquaintances who have read it and the content it leads them to a world of exploration and reach higher levels of intimacy as they are carried away by the imagination and practices that this book has.
It is a story in several volumes which is highly recommended if you like this style of explicit writing that if the case is not nothing that in today's society is not realized only in these books the taboo does not exist.
