Now that Meg has grown up to be pretty and has a husband and a baby on the way, she seems pretty secure in herself. Interesting. Honestly, I got really tired of Meg talking about her looks halfway through the first book. I'm sure the fact that she's grown up to be pretty like her mother is supposed to teach that things may look bad when you're young, but they get better when you grow up. What I got out of it, though, was that Meg's self-worth seems to be tied up in her looks.
Oh good gosh, this is when things really start to get boring. Most of the story takes place in Meg's head while she's kything with Charles Wallace who is in someone /else's/ head from the past. I don't even really know what went on for most of the story because (1 it was confusing as heck and (2 I was busy trying to keep myself awake. Basically, Charles Wallace's meddling in the past (which a unicorn permitted, so it's okay) prevents a nuclear war in the book's present.
I honestly felt like I'd wasted my time after finishing this one, and I was listening to it at work, so there was plenty of time to waste.
