This is the third in Pfeffer's series about life on earth after an asteroid knocks the moon out of orbit. I loved Life As We Knew It and liked The Dead and the Gone okay. In This World she brings back the protagonists from the first two books, but I didn't recognize Alex from The Dead for the longest time. He isn't particularly likable in the new installment, and sadly, the whole thing is less compelling. Still, I'll read the fourth book before too long.
There is a library scene, where Miranda digs two books out of the abandoned reference section...and then rips out pages from them, but I guess she's forgiven since there was no electricity to power the photocopier. At least she respects the libe. "...I thought about having to break one of the windows to get in. That seemed horribly immoral as bad as breaking a window of a church."
I tried to remember how people found things out before the Internet existed. They had to have questions, after all, and they couldn't always ask their parents. Or teachers. Or librarians.
Librarians! Librarians always know how to find out things. That was their job even before the internet.
