This is the last of the Trader's Tales of Ishmael Horatio Wang, and it's the only one the contained real danger. Ishmael acquires a ship of his own, with a catch. He has to employ and "train" the daughter of his previous employer. But it turns out someone really wants them to fail and even die.
As usual, this is a well told tale. Worthy of many re-reads. I really wish I could look forward to more books about Ishmael.
