To Fire Called by Nathan Lowell.
I love these characters and this series.
Here is the description from Amazon:
A dead ship returns to the Deep Dark with a live crew.
Captain Ishmael Wang finally gets the Chernyakova out of the yard and embarks on a voyage into the Toe-Holds where the Confederated Planets Joint Committee on Trade has no authority. Where the law is whatever you say it is as long as you can enforce it.
Where he learns that some will do anything to hide their secrets and everybody has a secret.
--This is a great series. I will keep buying them as long as he writes him.
