Gods Above 

As Lieutenant Mark Mc Henry hovers in a twilight state between life and death, and a mysterious, bearded one-eyed man moves ghost-like through the ship with his own esoteric agenda, Captain Mackenzie Calhoun and Commander Elizabeth Shelby go head to head over the growing problem on Danter. There, the god-like creatures known only as ‘The Beings’ are building an increasing power base, and the question is whether they are potentially the greatest ally or the greatest threat that the Federation has ever known. When more aggressive races such as the Thallonians enter into the mix, threatening to send the entire galaxy spiralling into war over the miracle food called Ambrosia, only the starships Excalibur and Trident — with the aid of Ambassador Spock — can stave off a conflict that could crack apart the Federation.
