From publisher blurb:
The deep survey ship Dorogan has been missing for months. Suddenly it has been discovered in low orbit over a sparsely populated planet in the Sonora sector. Where has it been? And where is it's crew?
A salvage party was sent aboard and left in a hurry. They complained of strange occurrences aboard the vessel and refused to return to it. They swear that the ship is now haunted.
The Kamura Corporation owns this ship and wants the valuable data and maps that the ship has acquired. They are offering a substantial amount of money to visit the ship and bring these things back. Any salvage that the travelers can obtain from the ship is theirs to take. The only catch is that time is limited. This ship is in a decaying orbit and does not appear to be able to break out of it.
