"If you want to visit a sea garden . . . you'll have to get up really early." So begins a trip to a Pacific Northwest seashore to explore sea gardens, man-made reefs that create shallow pools where clams and other types of edible seafood are easily harvested at low tide. An adult tells a child about the history of sea gardening, how the practice dates back 3,500 years to ancient Indigenous peoples, and demonstrates how to roll small boulders down to the water's edge; harvest mollusks, sea cucumbers, and other delicacies; and keep the sea bed clean and productive. The digital illustrations feature black-ink characters silhouetted against brilliant yellow sunrises and vibrant landscapes and seascapes, with occasional overlays of transparent stencils that evoke traditional carving motifs. The tone encourages discovery, insight, and respect, as the child meets new creatures and learns about protecting the environment. This engaging tale is a natural for lessons about ecology and units on Indigenous peoples, and the illustrations will pop for story-hour audiences.
