McMahon’s illustrated children’s book follows a week in the life of coral as narrated by an inquisitive Polyp. Polyp, a “tiny sea animal,” explains how its ancestors began growing in the ocean 485 million years ago. It is the animal that, along with Atoll (mineral) and Algae (plant), forms coral. Beginning on Sunday, the narrative follows the trio’s day-to-day experiences over the course of a week, beginning with an innocent and enjoyable “soaking in the sun.” But the coral reefs quickly become sick as humans, animals, and factories expel more greenhouse gases—and thus more carbon mixes with the salt water to create toxic carbonic acid. This increase in carbon creates warmer water, until the ocean is eventually so hot that Polyp can no longer collect enough food to survive. But by the end of the week, Polyp is saved when some turquoise Alga “snuggles in to churn the sun into sugars to revive me” as La Niña and new Alga patterns “bring the reef a brighter hope.” Simple text alternates with full-color paintings of ocean life, with a particular focus on coral and algae. McMahon, who both writes and illustrates the book, uses a muted color palette that nevertheless saturates the images with deep color; glimpses of brown, brainlike algae and brighter, warmer colors slowly give way to lighter creams and beiges as Polyp begins the process of bleaching. Certain characteristics conjure a unique sense of humanness: “Bleaching is when I turn white from losing my vitality. You would too if your partner leaves you.” McMahon occasionally lapses into an inconsistent, sort-of rhyme (“Thursday’s warmer water triggers Algae and I to bicker on our reef that is sicker”) that can be a bit jarring. But the rich paintings and evocative phrases (“an ocean volcano burped up a bubble”; “Algae huddles in my pink cup”) ultimately relay the vivid joys and sorrows of a unique resource in imminent danger. A gorgeously illustrated primer that introduces the basics of coral and its destruction by environmental changes.
