In Great Waters by Kit Whitfield

In Great WatersBook – What would the world be like if there really were mermaids? No, really, what would that be like? That’s the question Kit Whitfield sets out to answer in her spectacular novel In Great Waters, an alternate history of the world where the royalty of Europe are all descended from the deepsmen, tribes of not-quite-human folk who live in the sea and who first rose to land in Venice in a time of political strife. Now – in something very like sixteenth-century England – a half-human, half-deepsman boy has been abandoned by the deepsman tribe that tried to raise him. He represents an opportunity – the chance to overthrow the incompetent, inbred crown prince before he has a chance to ruin the kingdom. The boy himself, however, may have some different plans.

This is a tremendously inventive story, not fantastical at all except for the existence of the deepsmen – if it were set in the future, you’d call it science fiction. The book explores the implications of its premise, but it never loses sight of the characters at the heart of the story: abandoned, bastard Henry and Princess Anne, both trapped by others’ expectations and fighting to define themselves on their own terms.
