Book excerpt: "Summer school is in session on Ellesmere Island, and Martha, one of Edie Kiglatuk's students, is missing. When Martha's body turns up in Lake Turngaluk, Edie and her sidekick, Derek Palliser, promise the grieving family they'll deliver justice. But Martha's deeply traditional Inuit father spurns them as outsiders. Meanwhile, bullheaded lawyer Sonia Gutierrez is on her own crusade to investigate Lake Turngaluk's decades-old toxicity. Was one of the soldiers stationed near the lake involved in Martha's murder? Or is a larger conspiracy afoot--one involving the Canadian government? Edie, Sonia, and Derek clamber over the rocky Arctic terrain under the twenty-four-hour summer sun to find Martha's killer, but not without risking their own lives in the pursuit."--Back cover.
