I'm not really sure how a person could possibly not love this book. For one, it's about secret spy kids. For another, it's awesome and hilarious. And finally (as if that weren't enough), it's about chocolate. Need I say more?

I also would like to add that I am pretty sure Pseudonymous Bosch and I are soul mates. It seems from reading this book that his love of dark chocolate is nearly as passionate as mine (from Q&A in the book's appendix: "Q: What is dark chocolate?" "A: Heaven on Earth."),

In the story This Book Is Not Good For You by Pseudonymous Bosch, Cass and Max-Ernest, two friends fond of adventure and full of curiosity, set off on their third adventure. In this book, Cass, Max-Ernest, and a new friend they made in their last adventure, Yo Yoji, search for the Tuning Fork, a magical tool used to make the most plain substance, like water, into something delicious, like chocolate. These three are sent on their adventure not knowing any information, but knowing that their enem ...more

This is a great book series for young adults (10-18) who like intriguing books without having adult themes (sex, drug use, mature language.) My daughter (11) is already reading at a high school/college level, and it's hard to find appropriate books for her. This author is hilarious.

This is such a great book!!! You never know what is going to happen next so it makes you want to just keep reading! But the ending sucks! They don't tell you the answer to the big problem, they leave you hanging but that was the last book in that series!!!

Summary: In this delicious third installment of the amazing Secret Series, Cassandra and Max-Ernest have to beat an evil chef, rescue enslaved kids from a chocolate plantation, and find a mythical tool known as the Tuning Fork.

My thoughts: This book is the third book in one of my all-time favorite series!! And it has chocolate!! With awesome characters, an interesting adventure and chocolate, this is an excellent combination!

I really enjoy this author (whoever they really are!) Just make sure you have some chocolate to eat while you read it because it talks all about chocolate!

This is the third in a series and a really quick read, mostly aimed for kids about 9-12. But I still enjoyed reading it myself because it’s something light, playful and a pretty good mystery/detective story as well.

This one continues to follow the story of Cassandra, Yo-Yoji and Max-Ernest. I won’t tell you much, seeing as the content of this book is highly secret (^^) but I will say it has something to do with a cursed Aztec artifact, an evil and deranged chef, a secret lair of cocoa-crazed mon

Once again the Secret Series did not fail to deliver. This book was a great read. Pseudonymous Bosch has a funny way of placing chapters out of order. The first chapter is actually chapter fifteen (I think.) This is interesting because it is like watching one of those movies where they start out with the climax and you get really intrigued, but then it goes back to the beginning and explains how they got to that climactic moment.

Anyhow, in this book Cassandra's mother is kidnapped and Cass, Max

This Book is Not Good for You, Pseudonymous Bosch

This Book is Not Good for You is the third puzzle-filled book in The Secret Series, in which Cass and Max-Ernest, two brave 11-year olds, set out to fulfill some very perplexing—and dangerous—missions.

What’s the ‘secret’ this time? I’m not allowed to tell, but it has to do with the most delicious chocolate in the entire world. And it gets better from there. Once her suspicions are aroused, Cass discovers the dastardly Ms. Mauvais is masquerading a

This book is like a race against time. Because something happened to Cass’s mom. I think this book is really good because like I stated earlier this book is like a race against time. Cass, Max Ernest and Yo-Yoji has to save Cass’s mom before time runs out. I think this book is suspenseful be this book is all about suspense and mystery. This book is a part of a series called the secret series. I would recommend this book to my friend from my old school because he lo

This book was SO GOOD. All the books in this series so far have just sucked me in 100%. These books are so unique, each one has a different twist and a different feel. I think this one gave some great character development for Cass and Max-Earnest. Yo-Yoji still has room to grow, but I'm sure that will come in the next two books! Every thing about this book was wonderful and I personally think it was better than the previous book. Can't wait until the next book!

It was mysterious and I always want to read it to find out what's next. I like how the author always chimes into the book, and talks about how he doesn't know about something, or if he wants to put his opinion. I recommend this to all of u guys its a really good series. But dont start with this one other ys it doesnt make sense.

Shelves: middle-grade
Cute addition to this series. As usual with the middle book in a series, it was not quite as good as the books before it, but I have hope for the rest of the series. And, really, it wasn't bad in any way. It just wasn't quite as good as the last book.

This is yet another amazing book in the secret series I have thoroughly enjoyed it and will say that there are plenty of cliffhangers and at some stages it was so amazing that I just couldn't put it down.

this is such a wonderful children's series full of quite mature undertones, real adventure, and heartwarming friendship. I love the world it's building up.

I only hope that the author resolves it satisfyingly.
I liked the pacing with this book, it is definitely more middle-grade but I still found it enjoyable. I would definitely recommend this series (you will definitely need to read the first two books to know what is going on) however if you do pick this up definitely remember that it is aimed at the younger generation so some of the jokes and plotline may be a little dull or childish but it's still a good book!

'This Book is Not Good for You' is the third book in the young adult 'Secrets Series' by Pseudonymous Bosch.

The previous book ended with Cass, Max-Ernest and their new friend Yo-Yogi, once again thwarting the plans of the Midnight Sun and keeping the Secret safe. This book picks up a little while later. Cass is working in her grandfather

Recommends it for: Gr. 5 and up
Well, I’ve done what I recommend students not do: begin a series with a book other than #1. I have not read the first two books, but I picked up this one because it was the most recent…and—ok-- I really didn’t realize it was a series. So, starting off with that deficiency, I still had no difficulty getting into the book. The Midnight Sun, the enemy, is trying to figure out a Secret that the Terces Society is trying to prevent them from getting. Cassandra is at the center of the Secret, but she ...more

Short and Simple Review
The Secret series continues and just like the last book, I found this one to be enjoyable. There is a lot of oddities going on in this book, just like the last one, and I found it amusing keeping track of all the weird situations that Cass and Max-Ernest end up in. I felt bad for Cass because her mother had been kidnapped and she couldn't tell anyone else what was happening. There is a lot of chocolate in this boo
