First Light by Rebecca Stead

First Light by Rebecca Stead will plunge you into two different new worlds and you'll not want to leave -- Greenland and Graceland. Greenland is where Peter, one of the narrators, moves with his father, a glaciologist, and his mother, a genetic scientist. The family takes off on an expedition where his father studies the effects of global warming on the glacier ice caps. Thea, the other narrator, lives in Gracehop, a world beneath the ice. Peter and Thea meet and their two different worlds start to collide as they begin to understand secrets hidden from them for generations. Stead describes the icy settings and glacial structures with vivid detail and color. After reading First Light, the reader will have a better understanding of the dangers of Global Warming: Steads research is convincing and troubling.
