Riley Abercrombie is determined to win—even if she must gulp down her nerves and speak in public. The Historical Society is having a contest with a cash prize and an all-expenses-paid trip. 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, 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 her sleuthing puts her in peril, she's going to need faith, friendship, and even forgiveness to get her through.
