Aoleon the Martian Girl: Part 1 First Contact by Brent LeVasseur

Gilbert lives amid Midwestern farms, and he's been having strange dreams about outer space. Maybe it's because of all the crop circles found in the surrounding fields. One night, he awakens and follows a strange light flying around in the sky. He's surprised to find a young Martian girl standing in the middle of his neighbor's field. Their meeting is interrupted by the angry farmer and his shotgun, so Gilbert hops aboard Aoleon's spaceship. His adventure is just beginning, as the alien eventually transports him to her home planet, Mars.

This book is the first one in a five-part series. The plot moves quickly, with plenty of action and humor, but readers must have a tolerance for silliness. Half of this book describes the Air Force chasing the spaceship with fighter jets and a new rocket designed to intercept UFOs. For Aoleon, it's just playtime, since her ship has superior technology. Her ship is controlled by her thoughts, can travel thousands of miles in seconds, and can instantly change directions without losing speed or control. I'm guessing the other books in the series may be strange, since some Martians have a plan to conquer Earth. However, our cows are a big part of it.
