Choose Your Own Adventure 3: Space And Beyond - R. A. Montgomery

You were born on a spaceship traveling between galaxies and raised by parents from two different planets.

How should you thwart a curse placed upon you? What do you do in the face of dinosaurs? How can you work as an agent of intergalactic peace?
