Guideposts publishes really good series of cozy mysteries involving consistent characters, and the Blue Hill Library series is no exception. The characters are believable and the kind of people that one would like to have as friends and neighbors.
The plot in "Off the Shelf" is believable, with a trail of suspects that lead the reader in various directions and - surprise! - the culprit will not be the person you might expect.
Authors used in this series all go by the Emily Thomas name, but are very good mystery writers, many of whom have written in some of Guideposts' other series.
Awesome! Young adults and adults alike who enjoy family-oriented, well-written cozy mysteries will enjoy this book, I highly recommend it!
