In 1959 my family moved & I did not to finish a library book I was reading. No title or author so slim clues but here goes: A boy, about 10 or 12, goes to live with his grandfather due to his Dad being made a manager at a soft drink plant (Coca Cola?) in the Philippines. His grandfather lived in desert, seemed like Arizona or possibly New Mexico & I believe it was a trailer a good ways out from town & boy rode bus to school. He had a friend nearby, a girl, & eventually they met an Indian boy who lived close by. They would slip out at night to watch the stars & just hang out together as kids do. One night they caught sight of what they were sure was a UFO landing out in the desert & they planned to head that way & see where it landed. That’s as far as I got! If this rings any bells with anyone, would appreciate a clue. It must have been a mid to late 1950’s book & I believe it was hardback, don’t remember a book cover if it had one. Thank you!
