As a computer nerd and lover of graphic novels, this was fantastic. Absolutely wonderful.

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 work through, and provide detailed explanation through their characters.

There was too much math in this for me. The radius of a circle, degrees, yikes! Math was never my strong suit.

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.)

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.

While Yang has written so many better works I can say that even though this series is mostly annoying he does keep you turning the page to find out what will happen next. Could our answers lie not here but in another dimension?

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 most powerful programming tool that Professor Bee has, they manage to find Hopper's missing father and some of the professor's other students. But while they are preoccupied, One-Zero gets his hands on the Turtle. With Eni's parents threatening to transfer him to another school (because Hopper and Josh are bad influences), Hopper's mother worried about her safety and distracted by the health of her newly rescued husband, can the Coders stay together long enough to put an end to One-Zero and his plans for good?

Like the other Secret Coders books, Potions and Parameters has plenty of explanations of coding concepts as Professor Bee teaches the Coders the skills they need to fight the villain. And there are pauses so that readers can work out the coding challenges themselves. For middle graders who enjoy graphic novels and have an interest in robots and coding, this is the perfect series.

Highly recommended for elementary school libraries and classrooms. I read an e-book provided by the publisher through NetGalley.
