Written in verse, Crank tells the story of good girl Kristina who gives in to her base urges while visiting her low-life dad and experiments with crank **because she likes a boy**. She refers to this deviant side of herself as "Bree." When she returns to her mom's, she is addicted and seeks out the company of a couple of boys who will be able to get her drugs. Life spirals downward. 
 Crank gives a startling and stark look at the ravages of addiction, like watching an inevitable wreck. The verse form limits tha depth of understanding of the character, but does lend itself to the feel of her emotions while high or crashing. I especially liked the indented lines that would form a second poem within the main poem. These indented verses would often be harsher or contradictory to the main poem, much like Kristina vs Bree seem in the story.
