What would you do if you could go anywhere, do anything?
Chicago 2039: Head Trip, a virtual travel service, promises exactly that to anyone willing to pay for it. Shelby Hutchinson, a young computer professional, loves the idea and can't wait to take a trip. She turns to her favorite video game for inspiration and travels to Berlin in 1985. With the assistance of a memorable Soviet agent named Tasha, Shelby learns that chasing spies through Cold War Europe might be a great adventure, but nothing is ever as easy as it seems. When her virtual trip takes an unexpected and dangerous turn, Shelby returns to everyday life, but finds that even that has been changed by her experience.
The biggest change comes in the form of a magazine reporter named Trish, who bears more than a slight resemblance to someone Shelby met once before. Together, they discover that Head Trip is hiding a secret, and when that secret turns deadly, will Shelby do whatever it takes to make everything right again? Will she risk everything and take one more Head Trip?
