Novum: Apocalypse: Book 5 (Novum: A Dystopian Undersea Saga)

If you asked the people of Civica what they fear more than the Novum; the mythical ship-eating creature that roams the black water beyond their colony's protective borders, they will tell you it is the Betas; a race of artificial humans created by their ancestors long ago and cast out after the destruction of Earth, the so-called Fall of Man. Now, in the midst of a bloody civil war, those same people have no idea what new danger is fast approaching their colony, and why the return of a small and unassuming cargo submarine called the Rogue Wave will either help trigger humanity's final apocalypse, or be the key to its future survival under the sea.
