Based on the fictional journals of Stefani Michel, Humming in Spanish is the third volume in Ginna's Lavandula Series. This multi-generational saga begins in the 1960s and is set in the fictional Sweet Farm, a Carmel Valley, California lavender farm of some local renown.

The farm is the home of an intertwining cast of characters all somehow related to the Wyman clan: farmers, artists, writers, musicians. Over six decades, they bond and clash in unusual ways as they create their lives one breath at a time and discover all kinds of new and/or puzzling things about each other every day.
