Sixth grader Riley Abercrombie is determined to win--even if she has to gulp down her nerves and speak in public. The Historical Society is having a contest with a cash prize and an all-expense paid trip to where her great-grandma once lived. But a winning essay about her brave relative, a Rosie the Riveter in World War II, may launch Riley on an adventure far bigger than she'd imagined. She soon finds herself in a real-life mystery. A famous tool, an antique rivet gun, is missing, and Riley is sure she can uncover the culprit. Chasing clues and suspects with her new friend Marcus through a museum's vintage artifacts and aircraft, Riley just might discover she needs more than good detective skills. Will she learn to trust God when the wrong person has been accused? Can she be brave in the face of danger like her beloved great-grandma? When the kids' sleuthing puts them in peril, they're going to need faith, friendship, and even forgiveness to get them through.
