Excerpt: p 226
Kara was crying and screaming, desperately turning the steering wheel. We were tossed about, none of us had bothered to put on our seat restraints in our rush to leave the party. The car skidded, then rolled when the shoulder turned to cliff. I was screaming, flying. Tumbling. Glass sprayed like a thousand knives, and the world had no up or down. The fear was so complete it webbed together our screams and motion. Flying free and the sickening thud of my skull on the ground. Or was it Kara I heard, landing next to me? And then the sounds of dripping, hissing and soft moans that seemed to hover in the air above me. And finally just blackness.
I never saw Kara and Locke again.
They are my witnesses. They alone know that I didn’t drive that night.
When Jenna begins to question why she has no memory of her past he mother tries to explain:
p 118 “You were burned so badly Jenna. We tried everything. Even with all the temporary grafts, you were losing so much fluid. The antibiotics weren’t working. By the time they got you to surgery your heart had stopped twice. They had the Bio Gel waiting. They saved as much as was still viable. The butterfly, Jenna. That’s what they call it. The heart of the brain. That you still have.” (p 119)
At the end of the story, you realize that because of their Adoration of Jenna Fox, two parents manipulated science and medicine to save the life of their only child.
