Hitting shelves next week are a picture book about penguins with problems, a middle grade novel in the vein of Chaucer, and a new dystopian YA from a bestselling author.

The Magic Word by Mac Barnett, illus. by Elise Parsley. Balzer + Bray, $17.99; ISBN 978-0-06-235484-6. “What’s the magic word?” It’s a cloying reminder about good manners from the powers that be. One night, the bratty hero of this picture book makes an important discovery: by saying “alakazoomba” instead of “please,” he can bypass the middleman and magically get whatever he wants.

The Lost House by B.B. Cronin. Viking, $17.99; ISBN 978-1-101-99921-9. In this picture book, readers help a grandfather bulldog and his two grandchildren find objects in the rooms of a cluttered mansion, a task rendered more complex here as the spreads are monochromatic.

Willa: The Story of Willa Cather, an American Writer by Amy Ehrlich, illus. by Wendell Minor. S&S/Wiseman, $16.99; ISBN 978-0-689-86573-2. In this early middle grade biography of Willa Cather (1873–1947), Ehrlich focuses on the impact the author’s youth had on her writing.

Fleming and Rohmann (Bulldozer’s Big Day) draw readers in to the ocean’s murky depths in search of a seldom-seen creature.

The Inquisitor’s Tale: Or, the Three Magical Children and Their Holy Dog by Adam Gidwitz, illus. by Hatem Aly. Dutton, $17.99; ISBN 978-0-525-42616-5. In 1242 France, weary travelers at an inn trade stories about three miraculous children and their dog, Gwenforte, who has returned from the dead. The children—Jeanne, a peasant girl who has visions of the future; William, an oblate of partial African heritage with uncanny strength; and Jacob, a Jewish boy with the power to heal the sick and injured—are the subject of much rumor and debate. Are they saints, frauds, or in league with the devil? The book earned a starred review from PW.

Marvin and the Moths by Matthew Holm and Jonathan Follett, illus. by Matthew Holm. Scholastic Press, $16.99; ISBN 978-0-545-87674-2. Babymouse illustrator Holm and Follett met in middle school, and this alternately goofy and suspenseful story introduces Marvin Watson, whose own middle school experience gets off to a poor start in this antic-laden illustrated novel.

Pug Meets Pig by Sue Lowell Gallion, illus. by Joyce Wan. Beach Lane, $17.99; ISBN 978-1-4814-2066-2. This story about reluctant friends and the value of selflessness comes to life with Wan’s (The Whale in My Swimming Pool) pert, roly-poly characters, who look like something lifted out of readers’ own toy boxes. The book earned a starred review from PW.

Penguin Problems by Jory John, illus. by Lane Smith. Random House, $17.99; ISBN 978-0-553-51337-0. John (I Love You Already) delivers a series of laughs, and Smith’s (There Is a Tribe of Kids) mottled, minimalist polar landscapes highlight the penguin’s awkward moments. The story examines the delicate balancing act between total despair (“I have so many problems! And nobody even cares!” the penguin cries) and the resolve to stumble on.

Charmed, I’m Sure by Sarah Darer Littman. Aladdin, $17.99; ISBN 978-1-4814-5127-7.

Little Bot and Sparrow by Jake Parker. Roaring Brook, $17.99; ISBN 978-1-62672-367-2. “One day Little Bot wasn’t needed anymore. He was thrown out with the garbage.” That’s all Parker (The Little Snowplow) has to say about his droid’s backstory as he shows Little Bot tumbling through the air and landing unceremoniously on Earth, suggesting extraterrestrial origins. A bird named Sparrow spots the robot, whose face is an oversize monitor with doll-like features, and decides he “needed to be taken under her wing.” The book earned a starred review from PW.
