Shax can't walk away from an abandoned, hungry kitty. The fact that she can eat him in three bites is irrelevant.
Someone abandons a pedigree hellcat right where Shax can conveniently claim her and sets off a cataclysmic domino line of events. It's time for the other shoe to drop since the Brimstone has a shadow cabal after thempartly due to Shax's own, er, interesting decisions and partly due to the presence of Agent Julian Parallax onboard.
As ship security officer, Ness has a lot on his minda dangerous new pet, even more dangerous criminals tracking the Brimstone, and yet another unexpected rescued guest. The last thing he needs is a distraction and Julian, who confuses and confounds him more every moment, is exactly the distraction he doesn't need. Between Shax's reckless gambits and Julian's disregard for his own safety, how is Ness supposed to keep anyone safe?
The Brimstone and her intrepid crew do all they can to stay one step ahead, but this time the hunters are closing in.
