When a stolen Zero Point Module tears open a wound in time, the Doctor tracks his oldest enemy - the Master - to a legendary city in another galaxy.
Atlantis of the Ancients floats above an alien ocean, powered by technology that makes even a Time Lord wary. But the Master has never met a power source he didn't want to twist into a weapon, and a ZPM is the perfect key to rewrite history.
Stranded in the Pegasus Galaxy, the Doctor finds unlikely allies in Lt. Colonel John Sheppard, Dr Rodney McKay, and Ronon Dex. Together, they race through shimmering corridors, cloaked puddle jumpers, and swirling temporal storms as the Master prepares to fuse Time Lord science with Ancient tech.
If he succeeds, Atlantis will become a time fortress - and the first stone in a new, terrible empire.
