If you’re searching for a standout children’s book to add to your summer reading list, “Odder: An Otter’s Story” by bestselling author and 2025 CSLP (Collaborative Summer Library Program) Summer Reading Champion Katherine Applegate deserves your attention.

This beautifully adapted version of Applegate’s popular middle-grade novel brings the true stories of two otters from the Monterey Bay Aquarium to life in a way that’s meaningful for younger readers.

With its rich illustrations and thoughtful narrative, “Odder” offers not only an engaging story but also an educational glimpse into animal behavior and the effects of human interaction with the natural world.

John Newbery Medal winner Katherine Applegate’s gift for writing from the perspective of non-human characters — an approach that fosters empathy and emotional connection — is apparent. In “Odder: An Otter Story,” she masterfully explores complex themes like trauma and healing in a way that is both accessible and meaningful to young readers.

The story follows Odder, a spirited sea otter, from her early days to her dramatic rescue and rehabilitation by humans. Once released back into the wild, Odder’s trust in people, shaped by her time in captivity, leads her into dangerous situations, ultimately resulting in a serious injury.

Unable to return to the ocean, Odder faces a period of depression. But when she’s introduced to an orphaned otter pup, her world changes.

In caring for the pup, Odder rediscovers purpose and joy, becoming a surrogate mother. Through Odder’s journey, Applegate delivers a heartfelt narrative that speaks to the enduring power of compassion and second chances.

This story was truly brought to life, not only by the compelling narrative but by the beautiful illustrations. Known for illustrating books that deal with grief or difficult themes, illustrator Charles Santoso’s soft art style is phenomenal in this book.

Through vivid colors and semi-realistic images, Santoso carefully crafts the life of Odder. The illustrations showcase the effects humans have on Odder’s life while giving a beautiful visual of scientists trying their best to understand and help the young sea otter. Every image reflects the research, care, and heart that Santoso poured into this book.

Together, the story and illustrations create a deeply moving experience that stays with readers long after the final page. You can find the original middle-grade book anywhere in the Lincoln County Library System, and this wonderful adaptation at the Star Valley Branch Library and the Alpine Branch Library.
