Crank Ellen Hopkins, Glass Ellen Hopkins

In 
Crank
, Ellen Hopkins chronicles the turbulent and often disturbing relationship between Kristina, a character based on her own daughter, and the "monster," the highly addictive drug crystal meth, or "crank." Kristina is introduced to the drug while visiting her largely absent and ne'er-do-well father. While under the influence of the monster, Kristina discovers her sexy alter-ego, Bree: "there is no perfect daughter, / no gifted high school junior, / no Kristina Georgia Snow. / There is only Bree." Bree will do all the things good girl Kristina won't, including attracting the attention of dangerous boys who can provide her with a steady flow of crank.
Crank. Glass. Ice. Crystal. Whatever you call it, it's all the same: a monster. And once it's got hold of you, this monster will never let you go.
Kristina thinks she can control it. Now with a baby to care for, she's determined to be the one deciding when and how much, the one calling the shots. But the monster is too strong, and before she knows it, Kristina is back in its grips. She needs the monster to keep going, to face the pressures of day-to-day life. She needs it to feel alive.
Once again the monster takes over Kristina's life and she will do anything for it, including giving up the one person who gives her the unconditional love she craves -- her baby.
The sequel to Crank, this is the continuing story of Kristina and her descent back to hell. Told in verse, it's a harrowing and disturbing look at addiction and the damage that it inflicts.
