What does Liz see when she follows the light to its origin in the novel, Wooden Bones?

When Liz follows the light, she comes upon a wondrous place: An oil lamp lit row upon row of wooden carnival horses, all leaning against each other along one side of the barn. Their polished finish gleamed in the lamplight, heads cocked as though they were listening to the music. Their painted eyes seemed to turn in her direction.
