After 14-year-old Sophie leaves her home in Florida, where she lives with her father, to visit her mother's bonobo sanctuary in Congo, she rescues a young bonobo from its captor. Sophie names her new friend Otto and the two bond, but after civil war breaks out, Sophie and the young ape must flee from the sanctuary and attempt to survive in the jungle against overwhelming odds. With cruel revolutionaries everywhere, Sophie's life is constantly in danger. The story veers perhaps into improbability when Sophie, unwilling to abandon Otto, rejects two offers to leave the country. Still, Schrefer creates a vividly realized setting and a harrowing portrait of the chaos of a country at war. Best, though, is Schrefer's portrayal of the extraordinary bond between Sophie and Otto, and the close, awe-inspiring look at bonobos in general. Nature-loving teens will be captivated.

When Sophie, fourteen, arrives for her yearly visit to her Congolese mother's animal sanctuary, she becomes attached to a baby bonobo. So when the political situation destabilizes dangerously and she's scheduled to be airlifted back to Miami, she can't bear to leave him behind. Schrefer packs a wealth of incident into a compelling survival story set in contemporary conflict-ridden Congo.

Congolese-American Sophie makes a harrowing trek through a war-torn jungle to protect a young bonobo. On her way to spend the summer at the bonobo sanctuary her mother runs, 14-year-old Sophie rescues a sickly baby bonobo from a trafficker. Though her Congolese mother is not pleased Sophie paid for the ape, she is proud that Sophie works to bond with Otto, the baby. A week before Sophie's to return home to her father in Miami, her mother must take advantage of a charter flight to relocate some apes, and she leaves Sophie with Otto and the sanctuary workers. War breaks out, and after missing a U.N. flight out, Sophie must hide herself and Otto from violent militants and starving villagers. Unable to take Otto out of the country, she decides finding her mother hundreds of miles to the north is her only choice. Schrefer jumps from his usual teen suspense to craft this well-researched tale of jungle survival set during a fictional conflict in the Democratic Republic of Congo. Realistic characters (ape and human) deal with disturbing situations described in graphic, but never gratuitous detail. The lessons Sophie learns about her childhood home, love and what it means to be endangered will resonate with readers. Even if some hairbreadth escapes test credulity, this is a great next read for fans of our nearest ape cousins or survival adventure. (map, author's note, author Q&A) (Adventure. 12-16)

Schrefer (The Deadly Sister) shines a light on an oft-overlooked part of the world with this intense adventure set in the Democratic Republic of the Congo. When Sophie, a half-American, half-Congolese 14-year-old, visits her mother at a bonobo sanctuary, her biracial origins make her feel out of place, but she finds purpose by bonding with and caring for Otto, an abused juvenile bonobo. Civil war breaks out while Sophie-s mother is away, and Sophie is inadvertently trapped in a country beset by starvation, roving bands of killers, and natural hazards. To stay alive, Sophie and Otto live off the land, travel in secret, and coexist with other bonobos, while seeking escape or refuge from the chaos. Schrefer spares no detail, fully exposing the horrors of war as he chronicles Sophie-s struggle for survival. This drama is clearly written from the heart, smoothly educating readers about the perilous dichotomy of the Congo and the heart-wrenching plight of the endangered bonobo, without sacrificing the intensity of the story. Sophie, meanwhile, demonstrates herself to be tenacious, resourceful, and strong, making decisions that, while not always smart, are driven by compassion. Ages 12-18.

Gr 8 Up-Fourteen-year-old Sophie rescues Otto, a young chimp, while spending the summer at her mother's bonobo sanctuary in the Democratic Republic of Congo. When the president is assassinated and war breaks out, Sophie has a chance to return home to the United States but cannot bear to leave Otto. Their journey to safety takes them into the bonobo enclosure, but the real danger begins when they venture out and risk encountering rebel soldiers. Schrefer excels at imbuing the bonobos with individual personalities and endearing quirks. The bond between Sophie and Otto is so expertly depicted that it almost seems like a parent/child relationship, and readers will readily relate to the anguish the girl feels as she debates leaving her pet behind. The novel tackles tough ethical dilemmas without offering easy answers and delves into racial politics (Sophie's mixed racial heritage influences how others treat her), giving the book a nuanced tone. Schrefer portrays painful scenes in unflinching detail, and his powerful use of language drives the story forward. However, Sophie often seems preternaturally skilled for a teenager who has spent limited time in the Congo. Several moments stretch plausibility, such as when she rescues Otto from a group of soldiers or when she becomes leader of the bonobo tribe. Additionally, because Sophie is recounting the story as an adult looking back, her voice is often far more mature and polished than most adolescent protagonists. Yet despite the flaws, this is a poignant and moving story. Mahnaz Dar, School Library Journal
