Amelia is back in the present. However, her trip to the past cost her dearly. She's left the team and struck out on her own, determined not to make the mistakes of the past.
But the past isn't done with her yet.
A new threat has emerged. One that sells dangerous technology to the highest bidder . . . and they have their gaze set on Arsenal.
To face the threats of the future, she needs the most advanced Arsenal she's ever conceived.
That leaves her with only one choice . . .
Find a Th'un ship and use the metal to make her Alien Arsenal once more before her new enemy can. If she doesn't, she will lose more than her tech, she'll lose her life.
