Let's face it - if you're even considering reading this book, you've probably read the first 6 Twisp books. And if you've enjoyed the other Twisp books at all, you'll enjoy this one too.
As the title implies, this book follows the adventures of Scott Twisp, the son of Nick Twisp. The style is very familiar to the other books - it's a journal written by a teenager that's desperate to get with a beautiful girl. There are a few differences in the character of Scott than either Noell Wescott (aka Jake Twisp) or Nick Twisp. Mainly, Scott is a little bit more down to earth. Things don't get quite as drastically out of hand as they did with the previous protagonists. Somehow, though, C. D. Payne is able to keep this book as entertaining and hilarious as previous installments without being quite as outlandish.
Because this is the third protagonist in the Twisp series, there are A LOT of characters to keep straight. Pretty much any major character (and some minor characters) from the previous books makes an appearance. This didn't feel forced or awkward. It made me strain my memory to try to figure out who some of these people were, and in the end made me want to go back and read the earlier books again.
I really don't want to get into the plot at all - you know, because of spoilers and all. But if you enjoyed the other Twisp books, you'll definitely enjoy this one. If you haven't read the others, pick up "Youth in Revolt." It will only be a matter of time before you're picking up "Son of Youth in Revolt" also.
