The Stranger on the Ice

"Tour guide Valerie Blaine has always been haunted by the tragic death of her mother during an Arctic expedition thirty years before--unsolved, hushed up, and for Valerie, an unsettled part of a past she's never been able to escape. Its grip on Valerie is tighter than ever, now that she's been hired to lead a tourist group across the same desolate terrain where her mother died."--Page 4 of cover.
