Stargate Atlantis: Mirror, Mirror

When an Ancient prodigy gives the Atlantis expedition Charybdis - a device capable of eliminating the Wraith - it's an offer they can't refuse. But the experiment fails disastrously, threatening to unravel the fabric of the Pegasus Galaxy - and the entire universe beyond. Doctor Weir's team find themselves trapped and alone in very different versions of Atlantis, each fighting for their lives and their sanity in a galaxy falling apart at the seams.
