Look closely at the selfie that accompanies my Facebook posts or Amazon reviews (as JRAlpine) and you'll see this painting in the background. It plays a huge role in The South Rim Trail. Of course, you'll have to read the novel to learn all the details.
Terlingua Townhouse is a work in a style called plein air, and if you don't know what that means, that's yet another reason to read the novel. And if you do recognize the technique, you'll likely enjoy meeting some plein air painters in The South Rim Trail. The actual work is by award-winning artist Jill Carver, who does not appear in the book. But she has a splendid website and is represented by the InSight Gallery in Fredericksburg, Texas.
