Addison Anderson is a clever, cheerful girl, who is currently studying the castles of other countries. Having won a creative writing contest, and a free trip to Canada, she is curious to meet her Canadian challenger. To Addison's surprise, her very own cousin, Corby Clemens, comes through the door! While the Andersons visit the Clemens' clan, Corby's cat, Clover, disappears! Addison and Corby find clues that point to a Cat Burglar, and Corby's concern for Clover convinces him to call in the Royal Canadian Mounted Police. Corby is confident that with them on the job, the Cat Burglar will soon be caught, or will he? Addison books marry entertainment with education, structured in a unique manner that provides new vocabulary words and brief definitions on each page. With definitions on each page, it eliminates the hunt for unfamiliar word definitions at the back of the book. This new format empowers young readers and allows them to continue reading without timely disruption. Addison stories highlight one letter of the alphabet from beginning to end, with Addison's Canadian Caper highlighting words that begin with the letter "c." While reading these amusing tales, Addison books transport young readers to new locations, introduce other cultures, and share relatable situations.
