Highsong

A science-fiction novelette that’s basically a love letter to Ecco the Dolphin and Sea Quest DSV, with elements of Bug War thrown in.

Sia is a Risen, a genetically engineered, sapient (and psychic) dolphin on board a science-ship sent to check the stability of a terraformed planet, Ptaal, that lost contact with the Ninth Democracy 300 years before. Also on board is her human friend, Harp, the result of an illegal experiment that attempted to make a psychic human. Both of them look forward to their first mission, because none of the alien Viciss show signs of targeting Ptaal.

Sia and Harp are wrong.

Because the Viciss aren’t coming.

They’ve already arrived.
