Cricket is a little robot that functions as conscience to Eve Carpenter.
Cricket has mismatched eyes and a face that can’t show expressions. Still, he possesses metal slivers that pass for his eyebrows. The narrator describes him as a homunculus of spare parts, forty centimeters tall, the color of rust without any symmetry to him. His optics are too big for his head, and his head is too big for his body. The heat sinks on his back and across his scalp look like the spines of a porcupine.
