Countdown to Action! (Thunderbirds Series) Book

After his wife dies in a tragic accident, astronaut Jeff Tracy turns his grief into a dream: to create an organization which will rescue people that no one else can reach. He asks his five sons to give up promising careers to build the base, operate the machines, and serve in his organization. But he finds that in order to make his dream a reality, it will require sacrifice, courage, and determination... far beyond what he, or his sons, ever expected. Can they make International Rescue a reality, and what will it take to make the fantastic Thunderbirds machines GO?
