My rating: 3 of 5 stars
Book 3 of the Amazon Black Stars series of short speculative fiction stories. Not my favourite of the 4 that I have read so far. I liked the way it created an underwater city to which escaping landers were fleeing, paying for time limited, transit corridor opening licenses through hostile surrounding territory - a bit like a cross between the "40 acres and a mule" reparations promise to freed slaves and the Underground Railroad. On the other hand I felt it rushed in some parts, the premis requiring a longer piece to do it justice.
