Sea of Sorrows begun in 2496 and the rest took place in 2497.
They manage to capture their Xenomorph on LV-178 after stumbling upon the mine.
So I was confused to see this sample take place in 2351 with "Xenomorph samples from LV 178"
I'm just gonna pretend it's 2651 if the Rage War takes place in 2690's. I mean, Steve Perry admitted a timeline mistake in one of his books on a thread dedicated to asking him questions. Also remember the first AvP game set "ten years after Aliens" somewhere in 2150 something? I just say "screw it, it's 2189".
So Tim Lebbon could've made a similar mistake.
Also, like in Out of the Shadows, he spelled Alpha Centauri wrong, it's not "Alpha Centurai". I don't blame him though, isn't it the editor's job to correct this?
It's just one of them little mistakes we gotta learn to ignore, like the huge one in the Space Jockey pilot room in River of Pain. I'm still excited to get this book and this sample was quite a fine read as an appetiser.
And Ultramorph, I noticed the "Human Sphere" thing as well. I found that quite interesting as it shows our space expansion to go in a spherical motion sorta. I wonder just how big our territories are in the far future. And I hope to see some Arcturians in this trilogy, since there were "plans for them".
EDIT:
Upon reflecting, I realized that
Spoiler
this may not be Weyland-Yutani involved since they were "bought out by Wal-Mart" around this era.
And Sea of Sorrows implies they begun to rise after Resurrection.
So the year thing may not be an error after all. Liliya could be destroying samples obtained by a different organization similar to how Call tried to destroy samples obtained by the USM.
So, this different organization may have stumbled upon the mines before Weyland-Yutani but kept it under wraps. The fact that this is a decommissioned Colonial-Marine vessel (key word - decommissioned) may imply that this may be the USM or something similar?
So perhaps this 2351 setting is just a prologue and the rest will take place in the 2690's, the Founders may learn that Weyland-Yutani captured a xeno and could be trying to foil it.
