Margery Cuyler is the author of many books for children, including From Here to There, The Little Dump Truck, and the chapter book Weird Wolf. The idea for That's Good! That's Bad! came from a conversation with her son, Thomas, who asked, "Can't bad things change into good things?" Ms. Cuyler grew up in the oldest house in Princeton, NJ, and started writing stories as soon as she learned how to write. She now lives in the same house with her husband, sons and two cats.
