beating stop."

From the beginning, Steve suggests that he's writing the film script as a metaphor of how unreal and strange his life has become.

Sometimes I feel like I have walked into the middle of a movie. It is a strange movie with no plot and no beginnings.

He writes it as a film script because he associates film with famous people and outlandish story lines that could never happen to him in real life. It allows him to disassociate himself from events and even the crime that he may or may not have committed.

In that regard, Steve often uses irony to paint himself in a better light. For example, he writes dialogue showing the judge and the lawyers talking casually in court about what they did for the fourth of July as if they don't have care in the world. Moments later, they are adopting serious tones and caring attitudes towards their clients as they deliver their opening statements.

The word "monster" itself is a great example of figurative language in the book Monster. Steve constantly gets called monster, which can be interpreted as idiom, metaphor, or even hyperbole, depending on your perspective of Steve.

Steve's father reflecting on his dreams for Steve compared to the reality of it is a good example of imagery:

When you were first born, I would lie up in bed thinking about scenes of your life. You playing football. You going off to college. I used to think of you going to Morehouse and doing the same things I did when I was there. I never made the football team, but I thought—I dreamed you would.

Steve's father paints a small but concise picture of the perfect life that a father is supposed to imagine for his son. In just a few words , he illustrates very clearly what he expected and the ways this sits in contrast to Steve's life, indicating how much he has been let down.

This quote, from when the detectives are talking about Steve, is an example of idiom:

What are we playing with this guy for? We don't need him. We got the case locked.

"Playing with this guy" and "a locked case" are both idioms. Playing with is a non-literal way to describe the mental stress of dragging someone through the legal system. The case is considered "locked" because the detectives feel like they have all the information they need to achieve their desired outcome, not because it is physically secured with a key.

Walter Dean Myers includes numerous different types of figurative language in his novel Monster.

First, Myers includes imagery in the novel. Imagery is the use of descriptive language which appeals to the senses of the reader in order to help the reader create a mental image of what is being described. The opening scene of the novel exemplifies imagery. 

"The best time to cry is at night, when the lights are out and someone is being beaten up and screaming for help."

Here, Myers appeals to a reader's sense of sight (night) and sound (screaming). 

Allusion is also included in the text. An allusion is a reference to another work (thought to be known to the reader). In the novel, Star Wars is alluded to. The way that the text looks in the opening "credits" alludes to the opening of the Star Wars movie. This is important because Steve Harmon, the protagonist, openly states that "this is not a movie." 

Characterization is the way the author develops the characters within a text. In some cases, the author will use direct characterization (tell readers exactly who/what a character is). In other cases, the author will use indirect characterization (readers must infer about the character based upon actions, allusions, and dialogue). Steve characterizes himself as a monster (which is both a metaphor (comparison) and a hyperbole (an exaggeration)). That said, his actions do not support his claim.
