ALA Booklist

Here is a dystopian novel with a neat underwater twist. Nere and her mother, Gillian, live in a world almost destroyed by global warming and under the thumb of a totalitarian government, the Western Collective. Still, Nere can concentrate on her passion for dolphins (with whom she can telepathically communicate) until the ax falls. First, the government decides to move the residents of her area away from the sea. Then, Nere learns that she has been part of the Neptune Project. Gillian has altered Nere's genes so that she can be one of the first humans to live entirely underwater. With relocation imminent, Nere is given an injection that finishes her transformation. But no one has taken into account Nere's wishes. Feeling betrayed, Nere isn't sure that she wants to participate, nor does she want to swim across the sea to join the rest of the colony. Although the writing is pedestrian, the adventure element is a real draw. That Nere can experience regular kid situations throughout all of this iend issues, parental problems kes the story relatable, even if her best pals are (totally terrific) dolphins.

Horn Book

In a devastated postglobal warming country overtaken by a tyrannical government, Nere and her classmates, known as the Neptune children, are genetically altered to survive underwater and create a new human colony beneath the ocean. This fast-paced science fiction adventure with well-developed characters offers a vivid and exciting oceanic setting complete with villains, dangerous sea creatures, and protective dolphin friends.

Kirkus Reviews

Several centuries after global warming has devastated the planet, a tyrannical government has taken control of the West Coast of America. In a small seaside community in what was Southern California, Nere lives with her scientist mother and a pod of trained dolphins. Unbeknownst to Nere, her parents have genetically engineered her and several other children to breathe under water so they can live free there someday. When the government announces its intention to move the entire community inland, Nere's mother finishes the alterations on the children and sends them away into the sea, where they will try to join Nere's father's colony for these new "Neptune children." Nere and her friends, along with their friendly dolphins, must make their way there under the sea while fighting sharks and avoiding capture by government forces. They communicate telepathically, and Nere is even able to talk with the dolphins. Together with other Neptune children from Southern California, they head north, hiding and fighting all the way. Holyoke keeps her prose well-pitched to her audience, providing enough violence and even death to create suspense but muting it appropriately. She creates an interesting and diverse set of characters, including the dolphins. The science-fiction elements are nothing new, but they are built on good information about oceanography. This suspenseful, undersea dystopia should keep middle schoolers hooked. (Science fiction. 9-12)

School Library Journal

Gr 6-8 In this dystopian adventure, Earth can no longer sustain life in many places and the United States has devolved into a totalitarian government. Nere lives by the ocean and has always had an affinity for water. She thinks nothing of her comfort with the sea until the day her mother breaks the news that Nere is a product of a genetic-mutations experiment called the Neptune Project. Now the government wants to close down the project and kill all involved. Nere and two other children are given injections that finalize their mutations and enable them to breathe water. Their journey through the ocean to asylum isn't easy, but with some help from Nere's telepathically linked dolphin friends and other Neptune Project victims the kids just might make it-if they can stop quarreling among themselves. This is an enjoyable book, with lots of adventure, suspense, and underwater scenes. The novel hits the target audience right between the eyes on "hot button" issues, especially global warming and its consequences, but should be popular with readers who are looking for a slightly different dystopian adventure or those who just dream of living in the ocean and playing with dolphins.
