How does Janet Evanovich use imagery in Thanksgiving?

Imagery:

"The air was sweet with the smell of shaved wood, a nippy breeze played in the bare tree limbs, and the tower bells pealed noontime in Bruton Parish." pg. 94

"The aroma of roast turkey, savory dressing, and baking sweet potatoes mingled with the rich, smoky smell of the fire crackling in the fireplace. The autumn sky was gunmetal gray, but inside, the little house glowed with the patina of polished pewter chandeliers and copper kettles." pg. 126

"It was November, past the season of peak color for the foliage, and only a few hardy leaves remained on the trees. The new wintery image of lacy bare branches pressing against a brilliant azure sky caught Megan's attention as she tilted her head back, hoping for a few rays of warming sun on her face. A beautiful day, she decided, adjusting her mob cap. In fact, it was better than beautiful. It was perfect. A perfectly beautiful day." pg. 2
