The Dominion War #3 / Tunnel Through the Stars by John VornholtFrom the Gamma quadrant they came — hordes of fierce Jem’Hadar warriors commanded by the mysterious Changelings, who will stop at nothing to achieve victory over both the United Federation of Planets and the Klingon Empire. Now that the Dominion has entered into an unholy alliance with the Cardassian military regime and seized control of Deep Space Nine, Starfleet finds itself fighting a losing war against unbeatable odds. As mighty fleets clash in the deadly battleground of space, the fate of the entire Alpha Quadrant hangs in the balance. In the Federation’s time of greatest peril, as the Starship Enterprise readies itself for battle, Captain Jean-Luc Picard leads a desperate mission of espionage deep into the heart of the hostile Cardassian Empire. Unless they can prevent the Dominion from creating an artificial wormhole, hordes of fresh Jem’Hadar warriors and Changelings will pour into the Alpha Quadrant, dooming the Federation to unconditional surrender. But there may be a traitor along on the mission and Picard finds he cannot trust even his closest allies.
