Will Wilson’s Reviews > Alien: Colony War > Status Update

I think there are some time line issues with this book . They say the events of Alien happened 60 years ago but they also imply that Amanda Is still alive fighting the Xenos. Problem is alien isolation takes place 15 years after Alien making Amanda 26 in isolation so that would make her 71 ( my math may be off ) in this book? Also she is stated to be dead in the being of Aliens ( 57 years after Alien )
