2021 National Outdoor Book Award Winner in Nature and the Environment 2022 Washington State Book Award Winner in General Nonfiction Orca whale J35, also known as "Tahlequah," gave birth in July of 2018 in the waters off British Columbia, but her calf died soon after, leading its mother to carry her for 17 days across 1000 miles before finally releasing the calf and rejoining her pod. This extraordinary and caring behavior sparked not only worldwide sympathy, but also a revival of our awareness of the critical need to preserve orcas, the chinook salmon they feed on, and their habitat that together make up the core of Pacific Northwest identity. In "Orca: Shared Waters, Shared Home" journalist Lynda V. Mapes explores the natural history of the orca and the unique challenges for survival of the Southern Resident group that frequents Puget Sound.
