A book of spells. Memories in the snow. And nowhere to run. Lumi thought she'd escaped her past, but when she falls in love with a man from the far north, she leaves the safety of her life in libraries and follows him into the mysterious world of Arctic Town, a domed city where tourists play the part of frontiersmen and the birds watch her every move. Lumi begins making a home in the boreal wilderness, until the snow starts falling at autumn's end. To her dismay, each flake brings stray memories from other lives: The plague doctor. The homesteader with blood splattered on his walls. The charging bear with human eyes. And when Lumi finds out she is pregnant, her only escape is a grimoire, a book of spells that she knows she must keep hidden. But it all comes crashing down when Lumi's log cabin home is crushed in an avalanche and she is forced back on the run through the never-ending snow and a flood of memories threatens to drive her mad. Out in the snow, They start coming for her--the dark shapes between the shadows. Driven out, hungry, and at the edge of insanity, help comes from the least likely of allies and the memories begin to fall into place.
