Black Ocean Mission Pack 1 by J.S. Morin

Science to build a starship. Wizardry to take it past light speed. A crew to give it a soul.

The Mobius is a cobbled-together ship with a matching crew. Captain Carl Ramsey is an ex-Earth Navy pilot whose crew won’t let him fly his own ship. The pilot is his ex-wife, the mechanic is a drunk, and the chief of security is from a predatory species. Instead of a star-drive to travel through the astral space between worlds, the ship’s wizard does it by hand.
