Allison Lassieur has never had pop-star dreams, but she once sang in a choir that went on a multi-state tour on the way to Walt Disney World. Today she's an award-winning author of more than 150 history and non-fiction books about everything from Ancient Rome to the International Space Station. Her books have received several Kirkus starred reviews and Booklist recommendations, and her historical novel Journey to a Promised Land was awarded the 2020 Kansas Library Association Notable Book Award, and Library of Congress Great Reads Book selection. Allison lives in upstate New York with her husband, daughter, a scruffy, loveable mutt named Jingle Jack, and more books than she can count. Matt Doeden is a freelance author and editor from Minnesota. He's written numerous children's books on sports, music, current events, the military, extreme survival, and much more. His books Sandy Koufax (Twenty-First Century Books, 2006) and Tom Brady: Unlikely Champion (Twenty-First Century Books, 2011) were Junior Library Guild selections. Doeden began his career as a sports writer before turning to publishing. He lives in Minnesota with his wife and two children.
