I just finished reading the book. If you ignore the unlikely scenarios posed (mostly to do with Ripley's all too convenient participation in all of this) you will find that is a very fun book. It is one of the best "original" Alien stories that hasve come out in years. It would be great if they made this into a comic.
The glaring thing that struck me most was the following. Does anyone recall the convo that Ash, Parker, Lambert, and Ripley had about drawing straws because the Narcissus (kind of a Titanic flaw!) only has room for three? Well now it seems the Narcissus only has room for 1. One has to presume that when Ash, Parker, Lambert, and Ripley were talking about escaping in the Narcissus, they were talking about hibernation capsules for 3 and not just physical space for 3. If they were talking about physical space, it seems obvious that they could fit about 8 - 10 people in there. So just 1 hybernation capsule can't be right. Do I get a no-prize?
