First Light by Rebecca Stead is a compelling story told by two different narrators. First there is Peter, the only child of two talented scientist parents. His father, a glaciologist, receives a grant to travel to Greenland and study global warming. He takes along Peter and Peter's mother, a molecular biologist, who is writing a book about mitochondrial DNA. Peter, like any normal 7th grader, is excited to leave behind New York City for 6 weeks, but he's worried about his increasingly frequent headaches. Is he going to end up like his mother, whose headaches cause her to simply "check out" for days at a time?

Second, there is Thea, a 14 year-old girl who lives in Gracehope, a community entirely hidden under Greenland's ice. Thea's ancestors fled here a long time ago to escape persecution. Thea has never seen the sun. Her people's population has expanded to the point where resources must be severely rationed and births are limited. Thea feels that her people were meant to return to the surface, but her grandmother, who leads Gracehope, is set against expansion.

Peter and Thea's tales alternate as the plot's tension increases, and they eventually come together in this exciting story that mixes adventure with science and fantasy. Both characters are strong and independent thinkers, trying to make the best decisions with their limited knowledge. The adults in this novel seem strangely paralyzed by the past in many respects, unlike Peter and Thea, who are constantly looking forward to and advocating for the future.

You can read an excerpt from the book here and explore the world of First Light in its own Web site. A similar read is The City of Ember by Jeanne DuPrau. The library owns both the book and audiobook, which our family enjoyed listening to. Recommended for ages 10-14.
