Sleator's science fiction novels are noted for their unusual plots, which usually involve conflicts between young adults. Singularity is a tale of sibling rivalry which explores the value of individuality, the fear of the future, and the nature of time. It is an adventure-accomplishment romance, in which the protagonist develops and overcomes his own fears and bitterness; a suspenseful science fiction novel; and a "Robinsonade," a survival tale in which a character learns to live in isolation, much like Daniel Defoe's Robinson Crusoe. Despite its somewhat shallow characters, Singularity goes beyond mere formula and, as a result, makes interesting and satisfying reading.
