What makes this such a great series is that it does not rely on a set formula, and it focuses on character development and problem solving in addition to the enjoyment of animals. Though Lulu has met many animals throughout the volumes of the series, she has never had the same experience twice. This new story not only introduces an animal not often represented in fiction, but it also provides an opportunity to learn more about Lulu's community and her role within it. An animal may be at its center, but this is undoubtedly a story about people.
Lulu and the Hedgehog in the Rain shares similar themes with Violet Mackerel's Natural Habitat, and fans of one would easily enjoy the other. Even kids who do not traditionally enjoy animal stories will find themselves drawn to Lulu's unusual plan and the quirky people she must win over to make it a success.
