When Otter visits an aquarium with her adult-human minder, Otter Keeper, she's overjoyed by the prospect of meeting "animals that live in the sea." The book reads more like a tour of an aquarium than a story, although there's some drama when Otter's stuffed bear falls into Penguin Island. The spick-and-span art is good company for the immaculately simple sentences. (c) Copyright 2017. The Horn Book, Inc., a wholly owned subsidiary of Media Source, Inc. No redistribution permitted.
