I just read the best kid's book ever! My best friend sent it to us for Christmas as a gift, and I think it's hilarious in a tongue in cheek kind of way. Obviously, I'm not being paid or compensated for this review since it was a gift.
It's a Book by Lane Smith is marketed as a kid's book for ages 4-8, but if you have lost your sense of humor with using the word Jackass for a donkey it might be better for older readers like third to fifth grade. Since the younger children will likely yell out "Jackass" repeatedly out of context, and if it bugs you, or could become a public embarrassment, trade it out with "Donkey". I honestly thought it was hilarious and a smart play on words. I figure my son can say Jackass all day at home, and he already knows some words aren't for outside conversation. I've warned him if he says it in public (aka school) they will give him a red day and probably call me to get him. It works for us and the big bad swear words he knows are only for adults to say, so he doesn't.
Anyway, the book talks about technology versus old-school reading and it's pretty funny in it's simplistic way. Younger children probably won't understand the terminology "blogging" or "Wi-Fi", but my son knew about texting and tweeting. I explained the other words to him. He is a techie kid and at 4.5 years old he knows how to work a laptop and navigate his kid sites like PBSkids. So if you don't have a tech savvy kid and they're not familiar with the Internet or other technology, it won't be quite as fun comprehension-wise. I found It's a Book to be amusing rather than controversial and my son is excited about reading it, which is never a bad thing.
