The Neptune Project by Polly Holyoke (author) (US edition)

Love Sea Quest? Check out this cool sci-fi about three kids genetically altered to live in the sea. (Lots of great baddies too.) Aquatic action to the max. What do you want in your ultimate read? Does it go like this? Evil governments. Tick. Terrible enemies. Yup. Weird science experiments. Bring it on. Nere doesn’t know why she feels more at home swimming with dolphins than on land. Until she finds out she’s been mutated to survive under the sea. Here, she and the other Neptune Project kids will build a better future; safe from the barren country’s famine, wars and harsh laws. At least, that’s the idea…
