Cindy Neuschwander is the author of the Sir Cumference series, and she is also a third-grade teacher. Although she has never been trapped inside a pyramid, she has explored some in Egypt. Ms. Neuschwander lives with her family in Northern California. Bryan Langdo is the illustrator of several books for young readers. He is a big fan of mummy movies and lives in New Jersey with his wife. Together, Ms. Neuschwander and Mr. Lango have created three Adventures in Math picture books for Henry Holt. Patterns in Peru was published in Spring 2007, and Pastry School in Paris will be out in Spring 2009.
"The illustrations, by Bryan Langdo, are bright and clever, and there's a straightforward lesson in geometry built into the promise of Egypt. . . . very young Egyptologists will enjoy the archaeological atmosphere." --The New York Times Book Review
