There’s no reason why all the people humanity encounters in the universe should have the same relationship with space and time. Some Star Trek novel writers ignore this possibility, as the television series largely did, to comment on the problems facing humanity. Diane Duane doesn’t hesitate to comment on the human condition, but she does it while embracing the scope for imaginative effects that novels offer. Her human characters are fully human, and her alien characters are almost unimaginably alien. Duane’s examination of the mind-boggling diversity of the universe is set both beside and within her examination of the logistical difficulties inherent in schlepping 400 people into the unknown and getting most of them back again. Duane doesn’t just set her stories aboard the Starship Enterprise, she inventories the ship’s stores, consults with the Recreation Officer about morale, and holds inter-departmental planning meetings. She is endlessly fascinated with details and possibilities. When Diane Duane writes a Star Trek novel, she plays with all the colors in the Star Trek crayon box.
