Wow... this book just blew my mind! I don't think I've ever read such a heart wrenching series. Glass is the sequel to Crank, that I reviewed last month. This book is loosely based on Ellen Hopkins's own daughter's battle with drug addiction. Like I said in my first review this book has a lot of drug usage, sex scenes and a ton of other adult content/themes, so read with caution... Since this is book 2 in the series, the story picks up 6 months after the first book ends. We are re-introduced to the main character Kristina who is now a meager 17 years old! The book starts on a very positive note. We find Kristina is sober for the first time in a long time and her life has undergone some MASSIVE changes. Without giving too much away, some of these changes leave Kristina feeling a little depressed and trapped in her own life. She feels like a prisoner in her own house, and we find that she quickly turns back to "The Monster." In book one we see Kristina's introduction into the narcotics world, and we see how addicting substances can be. Book 2 was honestly just so shocking. We only go through 1 year of Kristina's life and it was such a crazy contrast from start to finish. As a reader you literally watch a life deteriorate. Drug abuse is a scary thing and I think using her own experience Ellen Hopkins captured this so vividly throughout her novel. Just the way she described Kristina's appearance in the beginning of the novel vs how she was described at the end is mind blowing! My heart truly goes out to Ellen Hopkins because even though this book is written loosely from her daughters perspective, I can't imagine what it would be like being the mother in this story. That's heart breaking to even think about... There is a third book to this series so I look forward to reading the rest of Kristina's story. A 5 star read for sure.
