Author’s Note: This is the black and white version of Gravity Drive 4 - Gus - This alternative format contains the exact same story and images as the original color version, except the images were converted to black and white to save on the ultra high cost of color printing. If you prefer the color version, you can easily access it through my Author’s Page at Amazon. Thank You. Gravity Drive 4 - Gus, is a spin-off novel from the original Gravity Drive trilogy, though it was written to be enjoyed as a stand alone novel for readers of all ages (devoid of violence, sexual references, and inappropriate language). The story bridges the timeline between Jason’s Ark (book 2), and The Scattering (book 3), though the bulk of the story happens within the time frame of The Scattering. In Gravity Drive 4 - Gus, a young Burrowing Owl named Gus, is orphaned from his family during the eruption of the Yellowstone Caldera, and is rescued by a young woman named Pepper. They climb into the Sierra Nevada mountains to escape the devastation being caused by the volcano only to discover that Pepper’s family had to evacuate their home and escape to the safety of an orbiting space station. Pepper is forced to make a series of survival decisions which take the pair through a progression of harrowing adventures including a daring sailplane ride, and a desperate escape on a mostly broken down space crane. They eventually make it to safety on an abandoned antique spaceship, only to discover it’s inhabited by the well known alien artificial intelligence known as Jason. After making themselves at home on the spaceship with Jason, they rescue a pilot who was thought to be lost, and together the four travel through a series of adventures that takes them to space stations, Earth’s Moon, Mars, and light years beyond the confines our solar system. Gus manages to cause hilarious trouble wherever he goes, but eventually proves himself to be the savior of a future world. The book is a story of survival during a critical time for humanity, and of the special bond that forms between two people and a quickly maturing little owl. The book is written as a science fiction novel for people interested in space exploration and the science of astrophysics. As a spin-off novel, it would naturally be most appreciated by first reading the original Gravity Drive trilogy. Thank you, and enjoy.
