I wanted to revive this cool thread. I will often continue to read an author when the setting is familiar and/or of interest.
For example, Still brought up Wallace Stegner, whose blizzardy book, Big Rock Candy Mountain, reminded me of my dad's stories of life in northern Minnesota - not bootleggers, but dirt poor, for sure, and characters I could place, culturally(though the book is not actually set in Minnesota, if memory serves.) Then as I continued to read Stegner, found his San Francisco, bay area connection in Angle of Repose, and a couple others. His son also wrote a book with similar, even more coastal, and closer locales.
Anne Lamott is a very nearby author, from Marin, many familiar scenes from her. Her books are so true and fabulous, I just love her. She's even close in age to me, so her recollections really resonate.
I'm neglecting some others that refuse to spring to mind, but I'll lastly mention Gary Soto, whose books include childhood scenes and comfort foods that are very dear to me, since we share a mexican family background.
