Summary:

Aperture Shutdown Book 1 is the first half of what is to become an interesting journey. However, in this first book, we discover that Wheatley managed to make it back to Earth from Space and decided to bring Chell back into the Enrichment Center through the Relaxation Chamber. He brings her through a few chambers and BTS vessels, while GLaDOS was observing those areas, thinking he could get to the area where he wanted to show us something.
