Riverwood is thriving, but Ronnie Deschaines senses impending changes in her orderly world as the next generation comes of age. Ronnie's husband, venture capitalist Luc Deschaines, buys a building on the Riverwalk in San Antonio when his daughter, Stephanie, approaches him with a business proposal that will have far-reaching effects on all their lives. Tim Hadley meets the former owner of his German Shepherd, and when he invites the boy home to see Maggie, it sets in motion a series of events that will change his family forever. Meanwhile, young Mia Hadley and best friend Hannah Rhodes have built a successful online quilting business—until Luc unwittingly ignites a passion for flying in Hannah, and the girls' lives diverge. And Texas is the last place Mia expected to find herself, so far from everything familiar. And what of Texas native Elena Sauseda? Will she return home to the Round Top Ranch after taking a summer job as a nanny to a wealthy family on Nantucket and matriculating at an exclusive eastern college? Or is she, too, destined to be a stranger in a strange land?
