Best Book Series For Adults Novels & Stories

Surprisingly, I don't find the idea disturbing. Feeling boredom as it sets in quickly, I make my way over to the bookshelf. I start to peruse the titles and am shocked at what I find. I see the House of Night Series, The Twilight Series, Forbidden Knowledge, Harry Potter Trilogy, and various books on Military Protocols all with black covers. The books are all in good condition too. Not interested in any of the military books I reach for the first book in the House of Night Series. As I take the book over to the couch to settle in, the door swings open.
