News has spread of Hudson and Liberty's unique ability to discover new portals; now every relic hunter wants a slice of the action.

Starting out from Deimos Station near Mars, Hudson and Liberty take the Orion to a new portal world. But Logan Griff, and mercenaries Cutler Wendell and Tory Bellona, are still chasing them. This time, Griff wants more than just their heads, he wants the secret to finding new portals too.

Captured and imprisoned, Liberty must use all her skills and wits to escape a life of service to the Council, the galaxy's deadliest criminal gang. But she discovers an ally in the most unlikely place.

Meanwhile, the mysterious alien entity known as Morphus returns. It agrees to assist Hudson in rescuing Liberty, but in return it needs his help too.

The stakes are even higher than Hudson imagined. A mighty force is returning, bent on the total annihilation of humanity. Its name is Goliath.
