This new tribe, however, has no feathers. They are mammals, and if the individual had not succeeded in teaching her bits of its language, she would not have believed such a thing possible. When the mammal found her injured and grounded, it offered food, protection, and the fundamentals of its language, allowing her partner, Quickwit, to return home and seek help.Mark Rollins has come with his parents to settle on a planet the government of Earth calls Tigris. It's a great adventure. Full of exploration and helping his parents build a new life.
