Alone is the first book in The Girl in the Box series. It features Sienna Neaslon, 17 year old girl, that was locked in her home for the past 12 years by her mother. Few days after her mom disappears, two guy come barging in, shooting her and she barely escapes with help of stranger. They go to the mall, where she is attacked by the huge beast like guy Wolfe and saved by the same guys that shoot her in the first place. She is then taken to the Directorate, weird agency that deals with people that have special powers. Apparently she is really strong meta human (people with special powers). 
 It is really quick read, more of a guilty pleasure book for me. I wished the story and the characters were a bit more developed and that Sienna wasn't such an unlikable character, I mean there is a difference between bitchy and bad-ass. 
 Also there is strong resemblance to x-men (special powers people) and Flash (meta humans). 
 Not a bad book, not amazing ether. Something quick to read when you are between books. 
 And despite of all of that I read the second one right away. :)
