The UnSeen by T.L. Hines

Lucas has lived most of his life being unseen. He likes the small hidden crevasses above the office spaces in the metro D.C. area. Being able to spy on others is one of his passions. Although he means no harm to them. Since Lucas has no permanent address he sleeps in underground tunnels and vacant buildings. He meets another "infiltrator" Donovan, and is drawn to him. Donovan introduces him to the Creep Club whose members watch and record people in their homes . . . The one place Lucas never wanted to do. While this is something he doesn't want to do he is drawn to them. As with all things, plans spiral out of control and Lucas is forced to figure a way out of the mess.
This is the first book I've ever read by T.L. Hines, and let me tell you it was a thrill ride from page 1! I give this book a lighthouse and shine a light on it for a great book.
