How does the author use imagery in the novel, The Wedding Date?

Example of Imagery:

"Alexa danced with Lauren, letting the movement and the laughter shake away her annoying thoughts. When she felt a hand on her waist, she turned to see Drew behind her and laughed again, at how ridiculous the evening had been and how much fun she was suddenly having. He took hold of one of her hands and swung her around to face him and laughed back down at her. Other members of the wedding party joined their group and danced with and around them, but song after song came on, and he never moved from her side” (62).
