When you want to engage students in history, give them a little mystery. That’s what Summerlin resident Kay Moore does every time she writes a book for young people. An educator before retiring in 2013, she knows how to bring that spark to a young person’s eye with tidbits from history. Her first two books were published by Scholastic as part of its “If You Lived” series. Besides being used in schools, her books are sold in gift shops at historical sites. Each has sold over 700,000 copies, and both are in second printings.
