Stargate SG-1: Roswell

Publishers summary
When a Stargate malfunction throws Lieutenant Colonel Cameron Mitchell, Dr. Daniel Jackson, Lt. Colonel Sam Carter, and Teal'c back in time, they only have minutes to live.

But their rescue, by an unlikely duo - Major General Jack O'Neill and Vala Mal Doran - is only the beginning of their problems. Ordered to rescue an Asgard also marooned in 1947, SG-1 find themselves at the mercy of history. While Jack, Daniel, Sam and Teal'c become embroiled in the Roswell aliens conspiracy, Cam and Vala are stranded in another timeline, desparately searching for a way home. As the effects of their interference ripple through time, the consequences for the future are catastrophic.

Trapped in the past, SG-1 can only watch as their world is overrun by a terrible invader...

Plot
Ultimately, with the help of An, the Asgard, and Cameron Mitchell, who after eventually travelling through the Stargate with Vala in an attempt to fix history, became Qetesh's First Prime. They manage to stop the invasion, which is led by Qetesh, who plans to assassinate Ra. Using Asgard beaming technology, they manage to beam 1947 nukes on board both of the Ha'tak in orbit, destroying them, killing Ra and Qetesh. Mitchell manages to get his hands on a time travel device and, unable to signal a beam out as he lost his radio, rings down to New York before Ra's ship is destroyed. With that done, Daniel, Teal'c and Carter travel to the past where the right Mitchell and Vala are stuck and beam them and a man that shouldn't have died but did in fire they caused aboard. Vala uses a Goa'uld healing device to heal his injuries from the fire and SG-1 beams him back and then returns to their own corrected time, taking An with them.

Deleted extracts
Sonny Whitelaw released two deleted extracts through her website, once Fandemonium had published the book. The extracts were removed from the final story for various reasons, mostly because they where unecessary to the furtherance of the story, and interrupted the pace of narrative.

First Deleted extract
Carefully injecting only minimal interest in his voice, Jack said, “And…?” Too much enthusiasm and he’d get the entire history of the Egyptian pyramids. Again.

Second deleted extract
“Don’t you see? The discovery of Tutankhamen’s tomb—while not necessarily the most significant—was, and still is, the most famous of the Egyptian finds. His funerary mask became iconic, as, too, have the countless tales of impropriety and the largely fictional ‘curse of the mummy’.”
