This is the second E.L. Konigsburg book I've read, and there's something very peculiar about her writing style. I can't put my finger on it. There's a real 80s-ish feel to it all, which sounds strange, but there's a real sense of children's books that were written in the late 70s to the early 90s.
So the narrator of our novel, Max/Bo, suffers from Little Man Syndrome in that he's about 12 years old, and he's simultaneously much older for his age and much younger. He's a pretentious little shit who is too big for his own boots and wears his freaking school blazer for the whole trip he's on with his father. Seriously, someone buy this kid a freaking Ivy League school sweater, as no one cares about the school you go to on the other side of the country. Never mind that it's the height of summer in Texas, no wonder you pass out.
The story itself isn't hugely interesting. The only thing that did capture my attention was Sabrina's story and the 'secret' behind why she keeps popping up. Nothing shocking (I thought her mother was a sex phone operator, but I guess that'd be too raunchy), but still interesting and just a little bit sad.
One final thing- if this book were released in modern times, I can't see it being recommended for ages 9 - 14. There's a tiny bit of swearing, a touch of sexual innuendo and just enough that I can see people getting up in arms about it. Fun!
