The coders are back in the third volume of the exciting new computer-programming series by New York Times–bestselling author Gene Luen Yang.

Stately Academy is just crawling with mysteries to be solved! In the last volume, Hopper and Eni discovered a robot in the supply closet and programmed him to do mischief. Now they're trapped in an underground lair, and they must use their new programming skills to escape. Hot on the heels of the highly anticipated first volume, Paths & Portals offers more of the same high-stakes adventure and real-world coding instruction. The Secret Coders series is an exciting new direction for Gene Luen Yang, one of the most popular creators in children's comics.

The third book in the Secret Coders series from Gene Luen Yang and Mike Holmes. Stately Academy is no ordinary school: it was once home to an elite institute where teachers, students, and robots worked together to unravel the mysteries of coding. Hopper, Eni, and Josh won't rest until they've learned the whole story, but they aren't the only ones interested in the school's past. Principal Dean is hot on their trail, demanding that the coders turn over their most powerful robot. Dean may be a creep, but he's nothing compared to the guy who's really in charge: a green-skinned coding genius named Professor One-Zero.

A nonbinary middle schooler saves a dog from bullies and is offered the chance to become the Dog Knight, protector of a magical pact between humans and dogs, in the first book of this humorous and heartwarming middle-grade graphic novel series from Jeremy Whitely, author of Princeless, and Bre Indigo, illustrator of Meg, Jo, Beth, and Amy: A Graphic Novel. Frankie knows who they are. They’re a drummer, they’re nonbinary, and they’re... the Dog Knight? One day Frankie is a relatively normal middle schooler, with relatively normal challenges, like finding the perfect outfit to wear during their drum solo during the upcoming band concert. The next, they save a friendly golden retriever from bullies and suddenly find themselves in a giant magical doghouse, with a funny looking helmet, talking to a group of dog superheroes called the Pawtheon about a job offer. If Frankie can prove that they possess the six dog virtues of loyalty, kindness, honesty, justice, stubbornness, and smell, they will be named the Dog Knight and be given the power to fight alongside the Pawtheon and save the world from the forces of chaos. Maybe there is more to Frankie than they thought?

The classic guide to how computers work, updated with new chapters and interactive graphics "For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think." - Scott Hanselman, Partner Program Director, Microsoft, and host of Hanselminutes Computers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating? For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use. This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend. In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World Brain From the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.

“A novelistic mosaic that simultaneously reads like a thriller and like a strange, dreamlike excursion into the subconscious.” —The New York Times Years ago, when House of Leaves was first being passed around, it was nothing more than a badly bundled heap of paper, parts of which would occasionally surface on the Internet. No one could have anticipated the small but devoted following this terrifying story would soon command. Starting with an odd assortment of marginalized youth -- musicians, tattoo artists, programmers, strippers, environmentalists, and adrenaline junkies -- the book eventually made its way into the hands of older generations, who not only found themselves in those strangely arranged pages but also discovered a way back into the lives of their estranged children. Now this astonishing novel is made available in book form, complete with the original colored words, vertical footnotes, and second and third appendices. The story remains unchanged, focusing on a young family that moves into a small home on Ash Tree Lane where they discover something is terribly wrong: their house is bigger on the inside than it is on the outside. Of course, neither Pulitzer Prize-winning photojournalist Will Navidson nor his companion Karen Green was prepared to face the consequences of that impossibility, until the day their two little children wandered off and their voices eerily began to return another story -- of creature darkness, of an ever-growing abyss behind a closet door, and of that unholy growl which soon enough would tear through their walls and consume all their dreams.
