Space biologists Jonathan Bartell and Gaby Larsen arrive at Johnson Base at the Moon's south pole for a project with Professor Isaacs that is so secret, he cannot share the details with them. However, the professor does not show up to meet them.

Vijay Singh borrowed money from a local council man who uses the debt to make continued threats to Vijay. In his despair to pay it back, Vijay gets involved with one of the most lucrative crime schemes in the solar system.

However, the capsule he retrieves from a crater near Johnson Base contains more than smuggled rare elements. But no one is going to talk about it for fear of getting on the wrong side of the crime lords. Even if keeping the secret will endanger the entire base.

This will appeal to readers of realistic adventure science fiction, like Robert Sawyer and Stephen Baxter. The books in this series can be read in any order.
