The Dark Land by Ronald A. Williams

Though Saint Euribius seems to be a quiet little island, its constant drama and intrigue tell a different story.  When a white political candidate runs for Parliament against a black man, tension and conflict are inevitable. And when a memoir, written by the ancestor of one of the candidates surfaces and reveals a hidden truth, the results quickly lead to danger on all fronts.  Throw in a rumored terrorist plot that is being investigated by an ex-army sniper, and there is suddenly much more than meets the eye in this sleepy tourist destination.  Everyone has a skeleton to hide, something in the past that is secret, hidden, or too personal to divulge.  What happens when those secrets go back to an 1816 slave rebellion?  What if those secrets are revealed by a current enemy with an agenda? In this dynamic page-turner, the truth is always just out of reach, and it is always deadly.
