Ice Trap by Kitty Sewell

Dafydd Woodruff is a doctor in Wales who gets a jolt from the past when he's contacted by Canadian teenager Miranda Hailey and informed that he's her father. Fourteen years ago, after he performed a botched operation on a young boy in England, Dafydd fled to Moose Creek in northern Canada, but returned to Wales after a short time. Miranda's letter causes a rift between Dafydd and his wife, Isabel, who have been trying to have a child of their own. Miranda's mother, Sheila, a nurse at Dafydd's Canadian hospital, is someone that Dafydd abhorred and he can't remember ever sleeping with her. However, when DNA results come back positive on Miranda's twin brother Mark, Dafydd knows that he must travel back to Canada to meet his supposed kids. Returning to the isolated outpost of Moose Creek brings back memories of Dafydd's time there and he is again immersed in Sheila's machinations and her intense dislike of him. Combining the story of Dafydd's past in Moose Creek along with the scenery of Canada's Northwest Territories makes for an interesting read.
