Below is a Book Trailer that grasps the elements of thrillers and suspense constantly used throughout the novel in order to create a successful "heart-racing" novel. 

Isolation is a reoccurring theme in Don't Turn Around where main characters deal with social isolation and its affects. The main character, sixteen-year old orphan, Noah jumps foster home to foster home due to the early death of her parents when she was just a baby. Eventually Noah becomes unhappy with foster care and uses her hacking skills and wit to maintain a lonely apartment life and a fake family so as not to deal with social services and the government. Although Noah does not mind being isolated from the rest of the world, it effects Noah in a way where she adopts major trust issues. When a new character named Peter Gregory gets personally involved with the secret company by identically coming across their experimental documents and website, Noah and Peter are forced to work together to figure out the ultimate goal to as why kids are being involuntarily experimented on. Noah, however, does not trust Peter at first where the book constantly writes, "But could she trust him? Really, could she trust either of them?" (Gagnon 179). Noah's isolation affects her ability to trust others due to her lack of human connections and social interaction. Noah truly transforms when she explains to Peter and his brother-like friend what has happened to her about where she was experimented  on and what she has discovered so far about the secret company. Trust plays a large part in the novel where no one can truly be trusted and everyone has to fend for themselves. 

Somebody's Watching Me- Rockwell (ft. Michael Jackson)
Who's watching
Tell me, who's watching
Who's watching me


I'm just an average man
With an average life
I work from nine to five
Hey, hell, I pay the price
All I want is to be left alone
In my average home
But why do I always feel
Like I'm in the twilight zone


And (I always feel like)
(Somebody's watching me)
And I have no privacy
Whooooa-oh-oh
(I always feel like)
(Somebody's watching me)
Tell me, is it just a dream


When I come home at night
I bolt the door real tight
People call me on the phone
I'm trying to avoid
But can the people on TV see me
Or am I just paranoid


When I'm in the shower
I'm afraid to wash my hair
'Cause I might open my eyes
And find someone standing there
People say I'm crazy
Just a little touched
But maybe showers remind me
Of Psycho too much
That's why


(I always feel like)
(Somebody's watching me)
And I have no privacy
Whooooa, oh-oh
(I always feel like)
(Somebody's watching me)
Who's playin' tricks on me

Analysis
Although this song is seen in present day Geico commercials and the tone of the original song is somewhat based on a not very serious  and humuorous atmosphere, it can be applied well to Don't Turn Around where the elements of trust and paranoia are commonly used. When Noah wakes up on a steel table in a warehouse with IVs stuck in her arm, she is both scared and ultimately confused. When she escapes the premises of the  foreign building she is constantly having to cover her tracks and hide; Noah is currently on the run from a secret company who ultimately want to capture her and use her for experimental purposes in order to find a cure for the disease of PEMA. This song represents Noah's paranoia of having the risk of someone constantly following her. Noah has to be aware of her surroundings and carefully travel to safe hidings to ultimately save her life.

The chorus above from Rockwell's song perfectly describes Noah's situation where she has no privacy due to the fact that she is unable to use bank accounts or have accesses to her house in order to avoid possible tracking from the secret organization chasing her. Noah has to closely  observe everyone around her just in case they happen to be part of the secret company; Noah always feels like somebody's watching her. 

Peter Gregory is one of the main characters in Don't turn Around who ultimately helps carry the story based on personal characteristics. Peter is similar to the character of Holden Caulfield from J.D. Salinger's Catcher and the Rye novel where he has to deal with his rich and selfish parents, has romantic problems, and ultimately wants to help the world be a better place. The characters also contrast in a way where Peter has to deal with trust issues based on the dishonesty of his parents and also romantic conflicts involving his heart break where Holden is usually the heart breaker and is not as passionate about romantic relationships. 

"If you've found this, then you’re already one of us. This won’t be an easy thread to follow. Because of the people we're up against, you’ll have to work for it. We’ll always leave bread crumbs, but they might get swept away, or be too hard to track. But we're trusting that even if you only find this entry, you’ll pass it along. Because the one thing we have going for us is numbers. There are more of us. And if we work together, we can stop them. 

I don’t like talking about myself, but I don’t have a choice anymore. I was taken by them. Experimented on. And I’m not the only one. They're preying on everyone outside the system, the kids no one cares about. 

Well, I care. And I am going to fight them. We're building an army, both here and in the real world. We're going to beat them at their own game. Even if you think you’re safe, even if you’re one of those people with parents and a social security  number and a warm place to sleep, you need to listen. Today, they're coming for us. Tomorrow, it might be you. So I’m asking for your help. I’m asking you to open your eyes, your ears. See what’s happening in every major city across the country. Kids are vanishing. Kids are dying. And the cops and the government are part of it. 

Follow me and we can save them. We’ll lead them back into the light. 

My name used to be Noa. But you can call me PER5EF0NE" (Gagnon 310)
