Acclaimed science writer and educator Dr. Lisa S. Gardiner sets a strong precedent for communicating the cutting-edge science of modern-day coral reef health in Reefs of Time. Through a lens of personal experience and discovery, Gardiner takes readers on expeditions to some of the world’s most endangered habitats. She masterfully weaves together recurring themes, such as the importance of community structure, dangers of bleaching events, and the fragility of reef ecosystems, while clearly explaining the geological principles by which fossils form and are preserved, and how these records help us better understand present-day processes.

Reefs of Time is an engaging and accessible exploration of the challenges coral reef ecosystems face under anthropogenically driven climate change. Gardiner addresses serious issues with humor and enthusiasm, using a diary-like style that feels conversational and draws the reader into the forefront. She skillfully balances scientific rigor with readability, grounding her discussion in well-cited literature without overwhelming those new to the topic.

The book is thoughtfully illustrated with both field photographs and cartoon depictions of more complex topics, making it approachable and visually engaging for a wide audience. As a scientist, I found this book enlightening, and I would also strongly recommend it to youth, particularly middle school readers (given the occasional adult humor), as well as to general audiences. This is because Gardiner highlights the scope and diversity of researchers' career paths, from engineers and geneticists to geologists and marine biologists, and emphasizes that collaborative innovation is essential to addressing environmental crises. Importantly, the book conveys a sense of humanity, portraying scientists not as distant figures but as creative, diverse, and interdisciplinary problem-solvers working together toward a solution to combat reef mortality.

Perhaps most notable is the book’s underlying message of resilience and hope, a sentiment we often overlook amid the challenges of climate action. Consistent and cohesive, Reefs of Time revisits its earlier themes throughout, building toward a powerful conclusion of collective action while celebrating the individuals and organizations dedicated to protecting and restoring coral reefs. Gardiner leaves readers informed, inspired, and optimistic about the possibilities of scientific innovation toward protecting our most vulnerable ecosystems.
