Bluebonnet, dubbed "everyone's favorite armadillo" by Texas Highways magazine, is off to visit Mount Vernon, Texas, in this tenth book of the Bluebonnet Armadillo Adventure series. When she arrives on the Daphne Prairie, she meets Dandy Don, a short-eared owl named for Mount Vernon's favorite native son, the late Don Meredith. The two nocturnal creatures take a night-time tour of historical sites, including pre-World War I homes, the Fire Station Museum, featuring the Don Meredith collection and the Nations Family Bird Egg Collection; the Cotton Belt Depot, The Bankhead Highway Trails and Visitor Center, Dupree Park Nature Preserve, Franklin County Courthouse, raised town plaza, and Majors-Parchman house. All along the tour, sounds and shadows suggest that someone has secretly joined the tour. Who is this mysterious follower? Readers will delight in searching for clues. The picture book provides an entertaining and informative story for young readers, with additional information about each historical site provided for older readers.
