A single piece of seaweed buoys a fascinating ecosystem in this nonfiction picture book from award-winning creators Barb Rosenstock and Katherine Roy.

From bryozoans and snails to shrimps, eels, swordfish, and whales, the Sargasso Sea provides a home to countless types of marine life, thanks to the prevalence of macroalgae called sargassum. Following a single blade of this extraordinary seaweed as it grows and spreads, readers see what it provides for the sea’s organisms: a base for hydroids and tube worms to filter and feed, shelter for anemones and nudibranchs and their nutritious waste, hunting grounds for crabs and amphipods, and a source of nourishment and protection for the fish, birds, whales, and reptiles that feed on these smaller creatures.

Through a widening scope on this intricate interdependence, Barb Rosenstock celebrates one of our planet’s most diverse and important ecosystems and the unassuming seaweed that sustains it. Gorgeously illustrated with Katherine Roy’s rich, eye-catching artwork, Sea Without a Shore is as fluid and rhythmic as the currents that shape this tidal home.

This groundbreaking book from award-winner Katherine Roy explains and demystifies how everything from fish to mammals and plants to insects reproduce.

From fish to mammals and plants to insects, every organism on Earth must reproduce, and the survival of each species—and of life itself—depends on this and on the diversity it creates. In this groundbreaking book, Katherine Roy distills the science of reproduction into its simplest components: organisms must meet, merge their DNA, and grow new individuals; and she thoughtfully highlights the astonishing variety of this process with examples from across the natural world, from plants to insects to fish, birds, mammals, and more.

Lucid, informed, and illuminated by beautiful paintings, Making More weaves a story that seamlessly explains life’s most fundamental process, answers children’s questions, and provides an essential tool for parents, caregivers, and educators.

Astronomer and astrophysicist Cecilia Payne was the first person to discover what burns at the heart of stars. But she didn’t start out as the groundbreaking scientist she would eventually become. She started out as a girl full of curiosity, hoping one day to unlock the mysteries of the universe.

With lyrical, evocative text by Kirsten W. Larson and extraordinary illustrations by award-winning illustrator Katherine Roy, this moving biography powerfully parallels the kindling of Cecilia Payne’s own curiosity and her scientific career with the process of a star’s birth, from mere possibility in an expanse of space to an eventual, breathtaking explosion of light.

WOMEN IN STEM CAN CHANGE HISTORY: With women making up less than 30 percent of the science and engineering workforce, supporting young girls who are interested in STEM fields is more important than ever! This picture book tells the story of Cecilia Payne, a trailblazing female astronomer and role model for young girls to relate to and see themselves in, from even the youngest age.

LOOK TO THE STARS: Any reader or stargazer who feels dazzled by the striking night sky will be enchanted by this true story of discovery and invention, as Cecilia’s contributions to science prompt us to wonder: What else is out there?

Red Rover is a gorgeously illustrated tale that explores the vast, inhospitable landscape of Mars and the adventures of the little rover that calls the planet its home.

Mars has a visitor.

It likes to roam…

observe…

measure…

and collect.

It explores the red landscape—
crossing plains, climbing hills,
and tracing the bottoms of
craters—in search of water
and life.

It is not the first to visit Mars.

It will not be the last.

But it might be…
the most curious.

Join Curiosity on its journey across the red planet in this innovative and dynamic nonfiction picture book by Richard Ho, illustrated by Sibert Honor winner Katherine Roy.

The savanna is not an easy place to live, even for African elephants, the largest land animals on earth. If it’s a challenge for these 7,000-pound giants, what’s it like for their newborn babies?

An infant elephant has precious little time to learn the incredible array of skills that are necessary to keep up, from projecting her voice across a 10-octave range to using the 100,000 muscles in her trunk to stay hydrated. But this giant-to-be has the perfect classroom–a family herd made up of her mother, sisters, cousins, and aunts. With their help and protection, she’ll learn how to survive, how to thrive, and how to be an elephant.

Award-winning author-illustrator Katherine Roy’s How to Be an Elephant delves into the intricate family dynamics at play in a typical African herd. Drawing upon the latest scientific research and Roy’s own expedition to Kenya, and brimming with lush watercolor illustrations and detailed diagrams, this book vividly portrays the life and development of an elephant from an uncertain newborn into a majestic adult. As informative as it is beautiful, Roy’s unique portrait of an elephant’s life will captivate young explorers and animal lovers alike.

Up close with the ocean’s most fearsome and famous predator and the scientists who study them-just twenty-six miles from the Golden Gate Bridge!

A few miles from San Francisco lives a population of the ocean’s largest and most famous predators. Each fall, while the city’s inhabitants dine on steaks, salads, and sandwiches, the great white sharks return to California’s Farallon Islands to dine on their favorite meal: the seals that live on the island’s rocky coasts. Massive, fast, and perfectly adapted to hunting after 11 million years of evolution, the great whites are among the planet’s most fearsome, fascinating, and least understood animals.

In the fall of 2012, Katherine Roy visited the Farallons with the scientists who study the islands’ shark population. She witnessed seal attacks, observed sharks being tagged in the wild, and got an up close look at the dramatic Farallons-a wildlife refuge that is strictly off-limits to all but the scientists who work there. Neighborhood Sharks is an intimate portrait of the life cycle, biology, and habitat of the great white shark, based on the latest research and an up-close visit with these amazing animals.
