Threshold Shift

I will hurt you more than you hurt me. Death will be a long time coming.

On the frontier planet of Threshold a hard won truce exists between the native inhabitants and the human settlers. When a murder puts this truce in jeopardy, Marshal Jacob Klein must try to see justice done, whatever the cost.

But Klein has his own problems - an addiction to a fatal narcotic, a disenfranchised son, and a dark secret he has been hiding for over two decades.

For there is a greater threat to Threshold than just a petty civil war. An ancient presence has invaded the planet for its own purposes and Jacob Klein is in no shape to stop it.
