The Horn Book Guide, Spring 2012

"Mitchell has done the secret world of espionage justice with these titles . . . Easy-to-read, informative titles."

School Library Journal, March 2012

"In this book author Susan K. Mitchell traces the history of codes, ciphers, and the men and women who attempt to break them. In telling this story Mitchell reveals just how complex many of these codes are . . . Mitchell also does a fine job of discussing Native American 'code talkers' whose unusual linguistics were used as clear code in World War II and several other innovative aspects of codes. Through these types of fascinating tales Susan K. Mitchell crafts a story about secret codes, their applications, and efforts to defeat them that will inform and entertain her readers."
