A young raccoon goes for an unexpected solo trip through a swamp. More interested in climbing into an abandoned boat than in digging for crawfish with his mother and siblings, the youngster is nevertheless distressed when his family’s efforts dislodge the mud holding the boat, sending him downstream. Arnosky (Wild and Swampy, 2000, etc.) uses a watercolor palette dominated by swampy greens to create a lush, self-contained world in which the surface of the water blends imperceptibly into the general background. The raccoon’s trip takes him—and young readers—past a microcosm of swamp wildlife both malignant and benign, including snakes, an alligator, a family of mergansers, and a bevy of wading birds, as all the while the raccoon’s family paces his progress from the shore. The all-encompassing green and the characteristically quiet, present-tense text effectively recreate the muffled, otherworldly atmosphere of a swamp. At the end, a relieved raccoon is reunited with his family, none the worse for his adventure. The events that lead to raccoon’s voyage seem somewhat contrived and at times his expression is just a tiny bit too anthropomorphic, but these are only little quibbles with a story that will resonate with young children still exploring their own boundaries while at the same time introducing them painlessly to an environment likely as unfamiliar as the North Pole.
