An idea that could help bring internet access to remote parts of the world takes Jack and his genius siblings deep into the Amazon rainforest in the final thrill-packed adventure in the New York Times bestselling series from Bill Nye and Gregory Mone!
Dr. Hank Witherspoon has disappeared. When Jack and his genius siblings, Ava and Matt, find Hank’s lab ransacked, they uncover clues pointing them to Brazil—but many questions remain. Why was Hank studying dangerous electric eels? And who is trying to steal his inventions? Their investigation leads them to a soccer prodigy, his savvy sister, a business tycoon who zips around on motorized boots, and a strangely incompetent riverboat captain.
In the depths of the Amazon rain forest, the three siblings and their new friends must overcome deadly piranhas, stealthy jaguars, and the dreaded “Trail of Pain” to save Hank . . . and make it out alive.
In the Jack and the Geniuses series, readers join Jack, Ava and Matt on adventures around the world to tackle some of science's biggest challenges, including new ways to create clean drinking water, to generate clean and renewable energy, and to extend information access to the entire planet. Each book in the series includes cool facts about the real-life science found in the story and a fun DIY project.

Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.

Excellent case! Perfect for what I needed, very stable, flexible and the color is great. I've had it for almost a year now and there's no damage or wear. Would buy again! Easy to use, stable mechanism to stand up right and wonderful color options!

Bright & Pretty Hot Pink.
Color: Pitaya Red, Color: Pitaya Red
Very pretty and bright. It’s thick and great quality. Strong grip and doesn’t come off easily. Easy to clean when it gets dirty. It also has a nice backing. I prefer the transparent bright pink backing than the clear version. I love the strong magnetic for when I position it upwards. It can be positioned downwards too.

Very protective iPad case
Color: 1-Navy Blue
This MoKo iPad case is excellent! It fits perfectly and provides great protection without adding bulk. The navy blue color looks very sleek, and the translucent back shell is a nice touch. It’s super magnetic, with great padding. The smart cover works flawlessly with the auto wake/sleep feature, and the cutouts line up perfectly for Touch ID. Lightweight, durable, and a fantastic value!
