Intruder

For some teen-age boys, a calm summer in the heart of Texas, becomes an interference with universal peace and harmony. A summer job on a Texas cattle ranch is not what it seems. They become a part of a sinister plan involving robotics research, and an alien portal hidden in a sturdy old oak tree. What seem like a series of coincidences eventually points to alien involvements. If there are beings from other planets, will they have things in common with human life? How will they communicate? Can they be good or evil? Are they smarter than humans? Do they even like humans? Is there an advantage to being friends with them? Grandpa Rex doesn't like change, but he has no choice but to accept it. His grandsons also have no choice. How would you handle life changing events caused by aliens from the planet Xeracik?
