Pages: 394

Pia has grown up in a secret laboratory hidden deep in the Amazon rain forest. She was raised by a team of scientists who have created her to be the start of a new immortal race. But on the night of her seventeenth birthday, Pia discovers a hole in the electric fence that surrounds her sterile home--and sneaks outside the compound for the first time in her life.

Free in the jungle, Pia meets Eio, a boy from a nearby village. Together, they embark on a race against time to discover the truth about Pia's origin--a truth with deadly consequences that will change their lives forever.

My teaser, from p. 189 in the hardcover:

Ami wades into the water to get a closer look.
Then I see it. "Ami, no! Get back!"
"What--"
She disappears under the water. In mere seconds a snake as thick as my thigh is coiled four times around her little body, and before my horrified eyes, it begins to tighten.
