Secret Coders is definitely coming to a climax as the stakes get higher and higher. While the kids have rescued Hopper's dad, they've lost the Turtle of Light and the kids feel like they might have lost their fight against the evil professor. On the other hand, Professor Bee has an idea! This is still a great series for beginner coding logic, and I quite enjoy the character development and plot shenanigans that accompany the more serious learning. Not so sure about the odd romance subplot that c ...more

I had high expectations for this book, as I have loved all of Gene Luen Yang's past books (at least those I've read). Sadly, I was let down a little. 

Check out my full review on my blog For the Love of Words.

Well I did not see THAT plot twist coming.

The Secret Coders use LightLight and their growing coding skills to help them hunt for Hopper’s dad, but things don’t go as planned and it is revealed that Dr. One-Zero has something even more evil in the works for the entire town.

Several big things happen in this one. The situation is getting more serious. Big secrets get revealed. The secret Professor Bee reveals was probably the most interesting (and unexpected). And everyone will be withering away waiting for Secret Coders #6 to come out. S

Hopper, Eni, and Josh continue their efforts to take down Dr. One-Zero before he can control the entire town. And that is just what he plans to do with his "green pop." He has the students creating gallons of the stuff during their chemistry classes, and readers already know from previous books that drinking the soda can hypnotize people into what the villain calls "true happiness." How does he plan to use this stockpile to take over everyone in town?

When the Coders use the Turtle of Light, the

Three friends try to stop an evil professor from poisoning their town by using their coding skills.

Full disclosure: I requested this book on NetGalley because I’ve read other Gene Luen Yang books and enjoyed them (American Born Chinese, Boxers & Saints). I want to learn more about the basics of coding, and I figured a graphic novel about coding by a great author would be a good way to dive in. I didn’t realize that this book is fifth in a series… and that you REALLY need to read all of the
The coding keeps getting more advanced, and the storyline keeps getting crazier! What will happen next? In this volume, they rescue Hopper's dad (yay!), thwart One-Zero multiple times as usual (yay!), and some start to realize they may have more-than-friends feelings for each other (which I could have done without. Do we really have to go down this path with every boy-girl friendship in books? Sometimes they're just friends! Let's focus on the coding and adventures!)

This was yet another fun tale of the Coders learning more code in order to take down the evil Dr. One-Zero. In all honesty, I thought this was the final book in the series, so I was very much looking forward to them taking him down for good, so when I found out it wasn't the end of the story and the next book still needs to come out, I was a bit sad.

That being said, the coding intensified and I learned more about repeats and variables and got a bit more lost than before, but I was entertained t

The Coders are back in their penultimate adventure where they must outwit ducks with teeth, discover a betrayal, recover a stolen item, and prepare to travel to another dimension- or is it one-dimension less?

I would say a reread of the previous books in the series is always a good idea before reading the latest one. This includes the bonus short story "Lost & Found" previously only available online.

I'm not sure if these are getting less exciting, or if it maybe it just feels like there isn't enough story in each book now, but I've been enjoying them less. They've always felt a little bit like the coding was tacked on, but this one is the worst for that so far, I think. (With "challenges" at the end of the major plot points.)

Further adventures of our three coders and Professor B. This time they stop the evil professor from contaminating the water reservoir and controlling everyone in the city. At the end, they learn that B is actually from another dimension - Flatland. The book ends with them figuring out the code to get to Flatland to get another triangle.
Certainly not the best in the series. I can appreciate its nod to Flatland, a point that does give a reasonable basis for the Turtle of Light, but I'm dubious that it will actually improve the plot or the narrative in upcoming installments.

2.5 stars rounded up.

I love how this series breaks down coding in a simple way yet also tells and interesting story. I do think readers would benefit from a “last time” refresher page as I questioned whether I read the last book or not when I started this one, even though it wasn’t too long ago when I read it.

3.5 stars. Love that these books get readers thinking about code!
Healthy dose of middle school awkwardness hits this issue. That Dr. One-Zero - watch out!

While we're talking about robots and programming, there's a new volume of Secret Coders coming at you. The fifth installment of the series sees Hopper, Eni, and Josh going up against Professor One-Zero and his evil Green Pop. The stakes are high, especially now that Hopper's dad's fate lies in the balance! We get a lot more of Professor Bee's origin, and the fight for the mystical Turtle of Light will keep you turning pages. Yang and Holmes challenge readers with more logic puzzles and codes to ...more

Love this series and how the story is developing with the coding problems.

I liked the style of the book. There are only three colors, green, white and black in the book.
The author/book designer has used different shades of each of the three to make an interesting combination of pictures.
I like learning about coding and binary because is it is interesting to me.
There is a lot of action and the characters in the book were funny.
I am looking to reading the next book in the series.
