The night charter - Sam Hawken

Meet Camaro Espinoza. She's spent her whole life protecting people: first at home, then in the army. Sometimes that means leaving bodies
behind. She'll be the best ally you ever have - but you don't want to be
on her bad side.

Right now she's running a boat off the Miami
shore, trying to keep a low profile. But then a man called Parker comes
to her offering good money, and bad trouble. Camaro doesn't want to get
involved, but Parker has a daughter who'll suffer if she refuses to
help.

When the job goes badly wrong, Camaro finds herself in the
midst of double crosses, international intrigue and scattered bullets. She's determined to save the girl's life... but it may be at the cost of
her own.
