The Dominion War by John Vornholt

This narrative centers on Captain Picard and his makeshift crew aboard the Orb of Peace, a civilian transport converted for a critical sabotage mission against a Dominion-built artificial wormhole. They navigate the treacherous Badlands, a region filled with plasma storms and derelict ships, encountering hostile Talavians and battling internal suspicions of a saboteur on board, ultimately revealed to be a Changeling posing as Taurik. Concurrently, Commander Riker on Starbase 209 grapples with the slow repair of the Enterprise and the emotional toll of the war, as Data undertakes a perilous solo journey to rendezvous with Picard. The climax involves Picard's team successfully destroying the wormhole, a costly victory marked by the death of Professor Grof and their narrow rescue by the Enterprise, which arrives just as they face imminent destruction by a Jem'Hadar warship.
