A Sister Would Know — C.J. Carmichael

She needs answers: With uncanny accuracy Amalie Fremont knows the exact moment her identical twin is swept away by an avalanche in the Canadian Rockies. What she doesn't know is what her timid, unathletic sister was doing up in the mountains in the first place. For everyone's sake, Amalie is determined to find out.

He's the man who can give them to her: Grant Thorlow, manager of the Avalanche Control Section at Rogers Pass, British Columbia, can help her. But he wishes Amalie had stayed put in Toronto. Her sister, it seems, caused nothing but trouble in the two months she lived at the Pass. The last thing he wants is Amalie here in town, kicking up a fuss.

Especially once it becomes clear to both of them that he can give her more than just answers about her sister -- and she wants more than that, too.
