Beloved and bestselling author John David Anderson returns with the conclusion to the epic sci-fi coming-of-age tale that began in Stowaway, which Booklist called "The Mandalorian meets Guardians of the Galaxy" in a starred review. Leo Fender is no stranger to catastrophe, whether it's the intergalactic war that took his mother's life or the ongoing fight for his own. He's seen his planet plundered, his ship attacked, his father kidnapped, and his brother go missing--and found himself stranded on a ship with a bunch of mercenary space pirates. Still, nothing could have prepared him for the moment he and the crew tried to save his father...and discovered a dark plot that could destroy hundreds of worlds in the blink of an eye. Now Leo is adrift. His father has sent him on a mission with nothing but a data chip and a name of someone who could help, and Captain Bastian Black and the crew of the Icarus are determined to see this through to the end with Leo, to fulfill his father's wish and prevent further conflict. But as Leo searches for answers, he can't help but wonder what it would take to end the war, to track down his father and brother and return to whatever home they have left--and if the cost of doing so is one he would be able to pay.
New York Times Book Review Editor's Choice “Kids won’t just love this book. They need it.” —Soman Chainani, New York Times bestselling author of The School for Good and Evil “Each page crackles as we embark on the greatest adventure of all.” —Gary D. Schmidt, Newbery Honor winner and author of Okay for Now Everyone knows there are different kinds of teachers. The boring ones, the mean ones, the ones who try too hard, the ones who stopped trying long ago. The ones you'll never remember, and the ones you want to forget. Ms. Bixby is none of these. She's the sort of teacher who makes you feel like school is somehow worthwhile. Who recognizes something in you that sometimes you don't even see in yourself. Who you never want to disappoint. What Ms. Bixby is, is one-of-a-kind. Topher, Brand, and Steve know this better than anyone. And so when Ms. Bixby unexpectedly announces that she won't be able to finish the school year, they come up with a risky plan, more of a quest, really, to give Ms. Bixby the last day she deserves. Through the three very different stories they tell, we begin to understand what Ms. Bixby means to each of them—and what the three of them mean to each other.

"When scientists discover a rare and mysterious mineral buried in the Earth's crust, they have no idea that it just happens to be the most valuable substance in the entire universe. It's not long before aliens show up . . . offering a promise of protection, some fabulous new technology, and entry into their intergalactic coalition--all in exchange for this precious resource. A material so precious that other alien forces are willing to start a war over it. A war that soon makes its way to Earth. . . . His mother was killed in one such attack, and soon after, his father, a Coalition scientist, decides it would be best for them to leave Earth behind. It's on this expedition that their ship is attacked, Leo's father is kidnapped, and Leo and his brother are stranded in the middle of space. The only chance they have is for Leo to stow away on a strange ship of mercenary space pirates bound for who knows where and beg the captain to help him find his father. But the road is dangerous, and pirates, of course, only look out for themselves. Leo must decide who to trust as he tries to stay alive and save his family, even as he comes to understand that there aren't many people--human or alien--that he can count on in this brave new universe"--Provided by publisher
The Avengers meets Louis Sachar in this hilarious and action-packed tween novel by John David Anderson, which Publishers Weekly called a "superhero story that any comics fan will enjoy" in a starred review. Andrew Bean might be a part of H.E.R.O., a secret organization for the training of superhero sidekicks, but that doesn't mean that life is all leaping tall buildings in single bounds. First, there's Drew's power: Possessed of super senses—his hearing, sight, taste, touch, and smell are the most powerful on the planet—he's literally the most sensitive kid in school. Then there's his superhero mentor, a former legend who now spends more time straddling barstools than fighting crime. Add in trying to keep his sidekick life a secret from everyone, including his parents, and the truth is clear: Middle school is a drag even with superpowers. But this is all before a supervillain long thought dead returns to the city of Justicia, superheroes begin disappearing at an alarming rate, and Drew's two identities threaten to crash head-on into each other. Drew has always found it pretty easy to separate right from wrong, good from evil. It's what a superhero does. But what happens when that line starts to disappear?
With multiple starred reviews, don't miss this humorous, poignant, and original contemporary story about bullying, broken friendships, social media, and the failures of communication between kids. From John David Anderson, author of the acclaimed Ms. Bixby’s Last Day. In middle school, words aren’t just words. They can be weapons. They can be gifts. The right words can win you friends or make you enemies. They can come back to haunt you. Sometimes they can change things forever. When cell phones are banned at Branton Middle School, Frost and his friends Deedee, Wolf, and Bench come up with a new way to communicate: leaving sticky notes for each other all around the school. It catches on, and soon all the kids in school are leaving notes—though for every kind and friendly one, there is a cutting and cruel one as well. In the middle of this, a new girl named Rose arrives at school and sits at Frost’s lunch table. Rose is not like anyone else at Branton Middle School, and it’s clear that the close circle of friends Frost has made for himself won’t easily hold another. As the sticky-note war escalates, and the pressure to choose sides mounts, Frost soon realizes that after this year, nothing will ever be the same.
From John David Anderson, acclaimed author of Posted, comes a ghost story pulled from the darkest shadows of middle school. Riley Flynn is alone. It feels like she's been on her own since sixth grade, when her best friend, Emily, ditched her for the cool girls. Girls who don't like Riley. Girls who decide one day to lock her in the science closet after hours, after everyone else has gone home. When Riley is finally able to escape, however, she finds that her horror story is only just beginning. All the school doors are locked, the windows won't budge, the phones are dead, and the lights aren't working. Through halls lit only by the narrow beam of her flashlight, Riley roams the building, seeking a way out, an answer, an explanation. And as she does, she starts to suspect she isn't alone after all. While she's always liked a good scary story, Riley knows there is no such thing as ghosts. But what else could explain the things happening in the school, the haunting force that seems to lurk in every shadow, around every corner? As she tries to find answers, she starts reliving moments that brought her to this night. Moments from her own life...and a life that is not her own.
