I don't really know what genre of books you're looking for, but maybe one of these will appeal?
Dance With the Devil by Sherrilyn Kenyon (it's a little way into the middle of a paranormal romance series, but I think it would stand alone rather well.)
A few books in Lara Adrian's Midnight, also paranormal romance, series take place in Alaska, but i don't currently remember which one(s)
In the contemporary romance genre, I would recommend the anthology Naughty or Nice, particularly Kenyon's contribution. While I don't think the stories take place in Alaska, they definitely involve snow.
Anyway, I hope I've been at least somewhat helpful.
