I was envisioning an image of a husky dog running across Arctic tundra in the summer. The dog should be running across grassy tundra which has some Arctic wildflowers, not a frozen snowy Arctic landscape. The dog should also have a leash dragging behind it. This is an emotional scene at the end of the book. There could be an iceberg on the Arctic Ocean in background.
There could also be an image of a 30-year old woman (Emma) who is (painfully and sadly( releasing the grip on the leash, watching the dog run away. Emma looks like Emma Stone the actress.
Another option would be an image of an Arctic flower, like purple saxifrage, with only one petal left, and a husky dog running away across Arctic tundra in background. The focus would be on the petal and the dog would be blurred.
A completely different idea could be a note on a kitchen table, with a tulips in a vase beside it. At the beginning of the novel, Adam disappears but he leaves a note on the kitchen table that says "Gone to get pancakes". It is the morning after Emma's 30 birthday, so there could be balloons or decorations in background.
