Probably only 3.5 stars. A cozy little Christian history/mystery involving a WWII-era secret and an old safe. Speaking of safe, this series is "caffeine free." There is absolutely nothing in this book that will trigger your atrial fib, unless your trigger is religion.
Nobody's Safe is pretty much an advertisement for the perfection which is Colorado -- somewhere between Xanadu and Shangri-la. Everything except the food, that is. On page 204, our protagonist, Sadie Speers, an antique dealer and amateur sleuth, goes to a place that, according to her, makes "the best pizza in Colorado" and she orders a Hawaiian. 🤢🤮
