8 and 6-year-old sisters named Twig and Turtle are excited and curious about their new small town in Colorado, and for their cool new tiny house. Their family is united in living more simply and not stressing out the earth's resources. And enjoying nature. But for Twig, that means leaving her BIG adopted Great Dane with her grandma. In the tiny house, there's barely enough room for a few books and games! Friendly and outgoing Turtle rolls with the move, and new life. But Twig struggles without her beloved dog. At school, Twig has to write about an opinion. And that gets her mind cooking. Twig is going to use her writing project to get her big dog back!
