Southern California is often associated with beaches, bungalows, and opulence, but there is more to the region than Los Angeles and Hollywood. Riverside, San Bernardino, and other often-overlooked areas reveal a Southern California of warehouses, workers, farms, and freeways that is home to diverse and deeply connected communities. In her latest book, “Mecca,” the celebrated novelist Susan Straight tells an epic story that captures these communities and explores the lives of native Californians navigating race, history, and family. Straight, who was born and raised in Riverside and still lives there, has been writing about Southern California and the Inland Empire for over 40 years. She shares some of that story with us.
