This last book had some pretty epic coding. I didn't follow it all, so I just skimmed it. I'm glad to be done with the series, mostly because of the creepy shapes. (I wasn't a fan of the added romance, either.)

My elementary students love all of the secret coder books. My sixth grade boys found this book (along with the others) to be great mentor texts for them to try and create their own novels around their passions!

A good graphic novel for those with a foundation in coding and great interest in the subject. Readers starting from the first in the series will probably have better luck understanding than those jumping in at this point.

I thought this was a great ending to the series. As usual, readers are asked to write code with Hopper, Eni, and Josh as they try to defeat Dr. One-Zero. The stakes have gotten higher and they have to come up with more complex code. Readers will learn about Modules and how they're used to make a program more efficient. The coding concepts are laid out in a visual way, which I think helps students understand an abstract subject.

Hopper, Eni, and Josh work with Professor Bee in their final showdown with the evil One-Zero. He has come up with another plan to release his dreadful Green Pop, only now he has an airborne variety! To defeat him they will have to travel to the professor's home dimension, Flatland, and retrieve another Turtle of Light to use in their battle with One-Zero. For those who have not heard of it before, the dimension that Professor Bee comes from is inspired by the satirical novel Flatland written by Edwin Abbott in 1884. In the country of Flatland the more sides a shape has, the higher its position in society, and women are only lines and not polygons at all. Professor Bee warns the kids that they will be converted into shapes and lines if they are successful in making the journey to Flatland. The problem with that is their lack of experience in being 2-dimensional beings, or in Hopper's case being a line!

And once they succeed, if they do, they will still have to return to the regular world and take on their nemesis. As if an arch villain isn't enough of a challenge, the kids have other problems. Hopper's father is still unresponsive in the hospital. Her mother is moving the whole family to another town. Eni's parents are sending him to a school that focuses on athletics, hoping to make him focus on basketball. Neither have told Josh about their parents' plans. And Hopper and Eni still haven't recovered from their awkwardness over Eni confessing his crush on Hopper. Things are never simple, are they?

This final book in the series brings all the forces to a head: parental expectations, friendship and crushes, an evil principal using the school to further his nefarious schemes, tyrants from another dimension... Along the way our heroes learn what real courage is all about, as well as coding skills like nesting commands and creating subprograms that can be used with more than one main program.

For those readers who have not tried coding before, Secret Coders is a fun introduction to the basic concepts used in creating computer programs. And for those who have, there are plenty of puzzles to solve as the Coders move from one challenge to the next. Everyone can visit the Secret Coders website to learn more.

Highly recommended for middle grade readers who enjoy graphic novels, school stories, and computers.

Hopper, Eni, and Josh must venture to the Flatlands to recover a Turtle of Light, their only hope in defeating Dr. One Zero before he bathes the entire city in Green Mist.

The students are going to be so sad to find out that this is the last Secret Coders. They love this series. I think it is pretty great too. It teaches the elements of coding in a very engaging way. By the time they get this far in the series they should be able to code just about any two dimensional figure, and they’ve learned about how subprograms can be useful. They’ve also gotten to follow around three friends who have had some pretty wild adventures. It’s a satisfactory conclusion to the series, even if readers will likely still beg for more. Who knows? With the way the series ended the coders don’t have to do what they do in secret any more so maybe there’ll be a continuing series called the Not-So-Secret Coders?

Notes on content: No language issues or sexual content. The only violence is really between two computer programs.

I received an ARC of this title from the publisher through NetGalley in exchange for an honest review.

This book is part of a series, and it is helpful to have read the earlier books, but not required. It's a great adventure story and dip of the toes in the coding world. That said, the books' talk about coding presupposes the reader knows about coding and, while not technical, may confuse the readers just looking for a fun graphic novel.

Review (by me and my children, who love this series): This book was a "little scary" but we really liked it. We just love these graphic novels, for both the story and the coding education. My 7 year old has been writing his own binary numbers and little codes, just on paper, inspired by the books! I recommend this series to everyone and buy the first couple books as birthday presents regularly. My kids declared this a satisfying end to the story!

In the epic finale, the Coders have to travel to another dimension, learn how to build a battle bot and take down the evil One-Zero! That all being said, after the boss battle (which was pretty awesome!), I found the ending a bit anticlimactic. I mean, it wrapped up all the loss ends, but just seemed rushed, especially with the three week time jump passing over some things. But that's just a tiny blip in an otherwise wonderful series! And I learned so much about coding! :-D

Monsters and Modules is an awesome finale for this exciting mystery/graphic novel/ STEM series. Students will love this installment as much as they loved the first. Learning about Flatland was exciting, especially when you are introduced to the Turtle of Light. Highly recommended for grades 3-6!

This is the final installment in the Secret Coders series. Coding-wise, we learn about sub-routines and put it all together. The story-line is more of a feature in this volume, and the kids use all the coding they have learned to bring the story to its conclusion. This is a really great intro to coding, just make sure you have all the volumes on hand and that kids read them in order!

My daughter loves Secret Coders and Monsters and Modules did not disappoint. Gene Luen Yang continues to develop the interest and enjoyment around coding. The mystery and problem solving involved in the book makes it more interactive and we loved it!

The Secret Coder Series is beloved in my Media Center. This final volume in the series focuses on the exploits of Hopper, Eni and Josh. They are using their programming skills by traveling to Flatland, a frightening world controlled by polygons in the hope that they can save humanity.
The illustrations and dialogue provide tools by which to teach shapes in an amusing, suspenseful way. What especially stands out is the explanation at the book's conclusion as to how the drawings were created.
I know my students will be quite disappointed that this is the final volume.
