Just: wow. I can't even label this with a genre.

SPOILER ALERT

I'm always up for a plausible time traveling story, and aspects of this initially made me think of Steven King's 11/22/63. I was willing to suspend disbelief when the protagonist traveled from the 1970s to 2001 so that she could have fetal surgery to make her pregnancy viable. I was even willing to humor the author's need to highlight how wacky all aspects of modern living would look to someone from the 70s.

But then... this becomes a book of terrible and selfish decisions. I even found myself hoping the whole thing would end up being told by a woman who was committed to a mental hospital because she had had a psychotic break and tried to kidnap a child who wasn't her own.
