A SWAP BETWEEN PLANETS - Bill Flynn

After a small UFO surveillance spaceship piloted by a robot crash lands in Nevada, NASA hires a private contractor engineer to analyze the electronics, software, and circuitry within the alien craft. After examining the spacecraft, she determines that it came from a planet named Trea. She discovers the transmitter method used to communicate from the spaceship to Planet Trea. Through a reverse engineering effort, she creates a space phone capable of communicating with Planet Trea. 

The revolutionary extraterrestrial communication device is sent to The Situation Room at The White House, where the president contacts the leader of Trea and discovers the planet is having an issue with global warming. They are in desperate need of lithium carbonate to power their shade cloud producing towers. 

The leader of Trea had learned, just before the spaceship's crashed, that an abundance of lithium is mined in the United States. Through their communication, the president learns that Trea possesses a cure for cancer in the form of a malignant scanner. Each planet has something the other desperately needs. Can these planets successfully swap resources for the betterment of both of their societies? A Swap Between Planets is an exciting read for science fiction lovers.
