A spy for the Typhon Pact--a new political rival of the
Federation--steals the plans for Starfleet's newest technological
advance: the slipstream drive. To stop the Typhon Pact from unlocking
the drive's secrets, Starfleet Intelligence recruits a pair of
genetically enhanced agents: Dr. Julian Bashir, of station Deep Space 9,
and Sarina Douglas, a woman whose talents Bashir helped bring to
fruition, and whom Bashir thinks of as his long-lost true love.
Bashir and Douglas are sent to infiltrate the mysterious species known
as the Breen, find the hidden slipstream project, and destroy it.
Meanwhile, light-years away, Captain Ezri Dax and her crew on the
U.S.S. Aventine play a dangerous game of cat and mouse with a Typhon
Pact fleet that stands between them and the safe retrieval of Bashir and
Douglas from hostile territory.
