Ridiculously predictable. 
 (view spoiler)[ When I read that Eugenie needed to take antibiotics after being injured in a scenario that I can't believe would be in any way dangerous to her given the things she has faced in the past, it was obvious she was going to get pregnant. What kind of idiot, who believes that the fate of humanity lies on the contraceptive powers of her birth control pills (dude, get sterilized if you don't want a baby that bad), doesn't realize that antibiotics affect the pill? It was like a bad teen movie from 1986. Then, of course, she discovers she's having twins, and decides she will abort them if female, or keep them if male. What do you know, it's one of each, and her doctor is apparently unaware that you can abort one fetus and keep the other. Or is it just that, with the fate of the world apparently resting on her unborn son's shoulders, Eugenie doesn't want the doctor to think she's having a sex selective abortion. (hide spoiler)] 
 I'm not sure I can handle reading the next book; the laziness of the plotting made me mad, but I do want to see what happens in the end.
