Through insider trading a scandal destroyed a highly regarded company and led to a depressed economy. The dip forced the Treasury to move massive finances to keep social security afloat. Layoffs and bankruptcies became the norm and leaders turned narrow-minded and short sighted.In 2017 scientists predict that an asteroid will ravage the earth in 2023 unless money is appropriated to create the technology to stop the destructive projectile. Visionaries from around the globe form an alliance to test various means to deflect the asteroid before it hits in six years. Soon the astronomers detect other asteroids heading towards the planet. The world needs heroes rather quickly or else face doomsday and both men and women quickly rise to meet the challenge. Falling Stars, the fourth book in this exciting series, brings all the characters back from the previous tales for a glorious finale. The story line is packed with non-stop action expected from a hard core science fiction novel, but surprisingly is character-driven as Michael Flynn emphasizes the staff as much as the quest. Though the conclusion of a strong quartet, this novel easily stand alone as a great genre entry.
