Checked this out at my local library to see if it had really anything more to add to the story and personally I’m glad I skipped on purchasing a copy because while it was interesting enough and maybe as a younger kid I’d be more into all the facts and details the almost try to bring you whimsically farther into the universe as a whole. But as an adult that’s sadly harder to do and with it not really giving much more from the previous works I’m not sure it needs to be read.

Haha, well...

I was thrift store shopping today, and somebody had donated a few 39 Clues books, this being one of them. I picked it up and debated on whether to buy it or not. During my debate with myself, I read through it. In, like, ten or fifteen minutes? There isn't a whole lot to read, most of it is stationary with letterheads from the different Cahill branches for "forging" letters from such-and-such-a-branch, and "check" pages for keeping track of which cards you've collected for the real-life scavenger hunt that took place when the series originally came out, as well as a bunch of code practice pages.

The only thing I really found interesting was that they put together some little mini-bios for some of the characters, including pictures of them. So I finally got to see what Irina Spasky, Ian Kabra (his personality stinks, but his looks...okay, stop), Natalie Kabra, Arthur and Hope Cahill, Hamilton Holt, Reagan Holt, Alistair Oh, Bae Oh, and William McIntyre look like. Well, in the case of Irina...looked like. Still can't get over that. Oh, and the ancestors of the individual branches as were painted on that mural Amy and Dan came across at the end of The Maze of Bones.

All in all, it was an interesting companion book, but I ended up deciding not to buy it. $2.50 for a used book that I don't really need? Psh, I'm not paying that. The Black Book of Buried Secrets is a much more useful book to have at hand whilst reading The 39 Clues, and I opted to buy that instead.

THE 39 CLUES ARE AN AWESOME SERIES BUT I THINK THIS ONE IS THE WORST AS ALL MY RATING IS COMPARED TO THE OTHER BOOKS

[Alex · Rating 5 out of 5]

I do not even know how to read this book i do know how to read it but i do not know were to click to read the book it stinks like shit

[Kryssy · Rating 4 out of 5]

This is the most unbiased documentation of everything that there could be. It mentions that each branch had a strong chance of collecting all the clues.

We also get a snapshot of the information we learned about each character over the last 10 books

Overall this was super fun as a fan of the book series! It clarified facts that we can never know if they’re true due to all the deception in the family.

- breakdown what each branch is known for
- Files of the cahills
- Grace and mcintyre performed tests on amy and dan to make sure they could handle themselves
- Hope had a microchip in her wrist
- Hope and arthur didn’t meet by coincidence
- Luke cahill went to be an advisor for Henry VIII, allowing descendants to be in the line of royalty
** i wish we had gotten more of irina before she died
- Each branch has assorted letterhead. I could write in the different people we know as those branches or the clues, or codes, etc
- Katherine and thomas were close until he had a family. She stole his clue which caused the branches to be sworn enemies
- No files on the starlings
- We never met the tomas branch leader
- The holts are considered outcasts
- More info on Reagan! We didn’t really learn too much about the sisters
- We get a file for cora wizard. Why not isabel? Or nellie?
- Many codes to solve that have been in prior books. Some new
- Pages to summarize info found out in each book including info on rival agents
- Released before book 10. So all details around that book are classified
- Checklist of the collectible cards

Why would you ever get this when The Black Book of Buried Secrets exists? This is just a worse and less convincing version of that.

[Natalie Tang · Rating 3 out of 5]

I could say its too violent but really it has just enough. This is a wonderful and Educational Book series. Many libraries have these books and the cards in them can be reused on anybody's account.

[Levi · Rating 2 out of 5]

not that good👾.

[Benjamin Auerzvald · Rating 2 out of 5]

Too much blank paper

[Adan H. · Rating 3 out of 5]

This book is about two kids named i Jasmine and Jake find out that their family is looking for 39 clues and those 39 clues will lead to a hidden treasure. I think this book was an okay book for me because it is adventures and kind of scary when people get lost or something happens to them. It is very amazing how they describe the book as if you were in it. For me this book made me feel excited and curios what is going to happen next. I would recommend this book to people that like or love adventures, scary, mistirous books.

[Kaylie · Rating 5 out of 5]

A good guide to the books and a place to put any suspicions or thoughts as your reading. It also gives you little secrets if you learn how to break the codes. It also gives a guide to all of the possible cards in the back of the book if you participate online.

[Rayhne A Tess · Rating 3 out of 5]

First of all, it doesn't even have all the cards from the first series to keep track of. Honestly the only thing I use it for is the biographies of the characters. Those are actually really interesting.

[Jake · Rating 4 out of 5]

Great companion book. Black and white though...

[Ruby Escalona · Rating 3 out of 5]

A notebook mostly than a book - it contains some facts about the various Cahill branches and features pages upon pages of clues that you could tackle!

[Charlotte Hui · Rating 5 out of 5]

It's good, and had a lot of information.

[Elise]

How do u read books? Please if you can tell me please do.

[Hayley · Rating 3 out of 5]

Not sure it was really that necessary to write this one. It mostly tells you a lot of things you already know but it's always cool to have a novella.

[Charles Unsworth · Rating 5 out of 5]

Great read.

[Ronah · Rating 3 out of 5]

It was more backstory for the 39 clues series. It was cool to read as a kid.

[Kieran20 · Rating 4 out of 5]

It is a handbook for taking notes about the 39 clues. You can only get it in the us.
