Tello, who unearthed Peru's ancient cultures and fostered pride in the country's Indigenous history. Growing up in the late 1800s, Julio Tello, an Indigenous boy, spent time exploring the caves and burial grounds in the foothills of the Peruvian Andes. Nothing scared Julio, not even the ancient human skulls he found. His bravery earned him the boyhood nickname Sharuko, which means "brave" in Quechua, the language of the Native people of Peru. At the age of twelve, Julio moved to Lima to continue his education. While in medical school, he discovered an article about the skulls he had found. The skulls had long ago been sent to Lima to be studied by scientists. The article renewed Julio's interest in his ancestry, and he decided to devote his medical skills to the study of Peru's Indigenous history. Over his lifetime, Julio Tello made many revolutionary discoveries at archaeological sites around Peru, and he worked to preserve the historical treasures he excavated. He showed that Peru's Indigenous cultures had been established thousands of years ago, disproving the popular belief that Peruvian culture had been introduced more recently from other countries. He fostered pride in his country's Indigenous ancestry, making him a hero to all Peruvians. Because of the brave man once known as Sharuko, people around the world today know of Peru's long history and its living cultural legacy.

A 2021 Newbery Honor Book In a moving, lyrical tale about the cost and fragility of freedom, a New York Times best-selling author and an acclaimed artist follow the life of a man who courageously shipped himself out of slavery. What have I to fear? My master broke every promise to me. I lost my beloved wife and our dear children. All, sold South. Neither my time nor my body is mine. The breath of life is all I have to lose. And bondage is suffocating me. Henry Brown wrote that long before he came to be known as Box, he "entered the world a slave." He was put to work as a child and passed down from one generation to the next -- as property. When he was an adult, his wife and children were sold away from him out of spite. Henry Brown watched as his family left bound in chains, headed to the deeper South. What more could be taken from him? But then hope -- and help -- came in the form of the Underground Railroad. Escape! In stanzas of six lines each, each line representing one side of a box, celebrated poet Carole Boston Weatherford powerfully narrates Henry Brown's story of how he came to send himself in a box from slavery to freedom. Strikingly illustrated in rich hues and patterns by artist Michele Wood, Box is augmented with historical records and an introductory excerpt from Henry's own writing as well as a time line, notes from the author and illustrator, and a bibliography.

When the sea otters disappear, why does their kelp forest habitat disappear, too? On the Pacific Coast of North America, sea otters play, dive, and hunt for sea urchins, crabs, abalone, and fish in the lush kelp forests beneath the waves. But there was a time when people hunted the otters almost to extinction. Without sea otters to eat them, an army of hungry sea urchins grew and destroyed entire kelp forests. Fish and other animals that depended on the kelp were lost, too. But when people protected the sea otters with new laws, their numbers began to recover, and so did the kelp forests. Susannah Buhrman-Deever offers a beautifully written account of a trophic cascade, which happens when the removal of a single element affects an entire habitat. Asides that dig deeper are woven throughout Matthew Trueman's dynamic illustrations, starring a raft of charismatic sea otters. Back matter includes more information about sea otters and kelp forests, including their importance and current status, the effects of the international fur trade on indigenous peoples, and a list of books and websites for readers who wish to continue to explore.

A Kirkus Reviews Best Middle Grade Book of 2019 A Japanese-American family, reeling from their ill treatment in the Japanese internment camps, gives up their American citizenship to move back to Hiroshima, unaware of the devastation wreaked by the atomic bomb in this piercing look at the aftermath of World War II by Newbery Medalist Cynthia Kadohata. World War II has ended, but while America has won the war, twelve-year-old Hanako feels lost. To her, the world, and her world, seems irrevocably broken. America, the only home she's ever known, imprisoned then rejected her and her family--and thousands of other innocent Americans--because of their Japanese heritage, because Japan had bombed Pearl Harbor, Hawaii. Japan, the country they've been forced to move to, the country they hope will be the family's saving grace, where they were supposed to start new and better lives, is in shambles because America dropped bombs of their own--one on Hiroshima unlike any other in history. And Hanako's grandparents live in a small village just outside the ravaged city. The country is starving, the black markets run rampant, and countless orphans beg for food on the streets, but how can Hanako help them when there is not even enough food for her own brother? Hanako feels she could crack under the pressure, but just because something is broken doesn't mean it can't be fixed. Cracks can make room for gold, her grandfather explains when he tells her about the tradition of kintsukuroi--fixing broken objects with gold lacquer, making them stronger and more beautiful than ever. As she struggles to adjust to find her place in a new world, Hanako will find that the gold can come in many forms, and family may be hers.
