Disappointing for Connie Willis. This is too convoluted, unwieldy, too many convenient details and events, and deus ex machina, and an annoying kid. On a topic like this one, things had to be tight, and there were many times where I thought (haha) this was not consistent. The constant back and forth of dialogue and thinking gets exhausting.
Also, the men saving women, that was also annoying.
ETA: after thinking about it further, this book is pretty much a rehash of Passage.
