The jungle hides a girl who cannot die.

An electrifying action-romance that's as thoughtful as it is tragic.

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.

Origin is a beautifully told, shocking new way to look at an age-old desire: to live forever, no matter the cost.

"ORIGIN is a startling mystery played out in the vivid and lush Amazon jungle. In this deadly clash of science and nature, a heroine emerges. Pia clawed her way through the pages and left her mark on the landscape of my imagination as the almost tangible danger left me breathless."--Colleen Houck, New York Times bestselling author of Tiger's Curse

"I loved Origin's action, romance, and mystery--and I couldn't stop thinking about the questions it raised." --Beth Revis, New York Times bestselling author of Across the Universe

"Is this science fiction? It feels too scarily real. This spellbinding tale of the horrors of genetic engineering gone made is both thriller and love story, breathlessly paced and beautifully told." --Judy Blundell, National Book Award-winning author of What I Saw and How I Lied

"A lush, dreamy page-turner that will live forever in the hearts of its readers. Pia may be the perfect antidote for those suffering from Katniss withdrawal." --Josh Sundquist, author of the national bestseller Just Don't Tell
