Crank by Ellen Hopkins

The #1 New York Times bestselling tale of addiction—the first in the Crank trilogy—from master poet Ellen Hopkins.

Life was good
before I
met
the monster.

After,
life
was great,
At
least 
for a little while.

Kristina Snow is the perfect daughter: gifted high school junior, quiet, never any trouble.

Then, Kristina meets the monster: crank. And what begins as a wild, ecstatic ride turns into a struggle through hell for her mind, her soul—her life.
