What is the author's style in Crank by Ellen Hopkins?

Hopkins makes powerful use of language in this story. One major example of this use of language is her reference to crank as a monster. By calling the drug a monster, Hopkins personifies the drug, giving it life and personality. For those who have experienced drug use or drug abuse, they realize this personification of a drug is quite correct. The drug is a monster in the way it takes control of a person in the form of addiction. The term "monster" also indicates crank is bad, scary, and should be avoided.
