I did this only for fun; the book is targeted to an audience that this wouldn't fit. I just liked the title, and the fact that the book is written by a 12-year-old.
The book is about a girl who in darkness becomes a monster. She tries to hide this fact, but falls under the watch of shadowy secret agents. Eventually, friends and family rescue her, and it transpires that they are all monsters, too.
In the cover, I just wanted to represent identity distortion. Similar to another cover I did a while back.
Maybe it's how I feel, oftentimes.
