The Unseen by T.L. Hines made me rethink what I thought was my own privacy. Are people lurking behind my walls? He uncovered a segment of society I’d not known before, mixing it with a mysterious protagonist with a sketchy past. Although I found him somewhat creepy, I wanted to root for him as he uncovered layers of secrets. Intelligent, quirky, and innovative, folks who like espionage novels with a tinge of the supernatural will love this book.
