Ruby & Nolan's Great Adventures in Space Book 4

Ruby, Nolan along with Mom and Dad, Robin and Ty, are invited to participate in an experiment: Travel to another galaxy to help settle on a new uninhabited world. Ruby and Nolan want to take their Uncle Dawnzereli, but could only take Pebbles their dog.
While doing their chores, they find a beautiful rock. Yikes! It hatches, and the baby dragon bonds with them, and they name it Donzereli. The fun begins when its parents arrive to take custody of their baby.
Will the settlers come to grips with the fact that they are not alone?
Ruby and Nolan, don’t care about adult things, they have a dragon friend! Donzereli invites them to fly to his mountain home. Ruby and Nolan and their friends Bonnie and Shamus are thrilled that several of his dragon friends lend their backs for the trip. Dr. Allen bribes an invitation to go with them. What could go wrong?
After all, they have an adult with them?
The children wonder why the dragons were so well prepared for them to stay several days if they aren’t happy to have house guests. When they are informed that their parents are on the way to take them home, they panic.
Donzereli plans a fun, deep sea fishing trip surprise for them without his parent's knowledge or permission. He “borrows” his parents flying car to add to their adventure. It’s just a fishing trip! What could go wrong? Could it be meeting the “Others?”
The others look like the Abominable Snowman but are humanlike. They all have a blast at the Amusement Park and are sorry to leave. All good things come to an end. Will this be the end of their adventures?
