First Light (Stead novel)

First Light is a young adult science fiction and mystery novel by Rebecca Stead, first published in 2007. The novel follows Peter, who is in Greenland with his father and mother for research on global warming, and Thea, who lives in Gracehope, an underground colony located below Greenland. First Light explains how global warming is melting Gracehope and Peter and Thea's attempt to persuade the people to leave. The novel addresses the effects of global warming as a theme.

Stead began writing the novel in 2002, but her first draft was confusing and unorganized. To help her, she met editor Wendy Lamb who advised her to meet with a small group of people who would help critique the novel. After three years of work, Stead finished the second draft and met with Lamb who once again helped make improvements and later published the novel. Reviewers praised the description of Gracehope and main characters, as well as the performances of Coleen Marlo and David Ackroyd who voiced Thea and Peter in a subsequent audiobook publication of First Light.
