Pay the Piper: Hathe Book Two by Mary Brock Jones
The war is over, but surviving the peace may be their toughest fight yet.
For five years, Earth ruled Hathe, taking what they needed, especially the energy-rich mineral, urgonium, it must have to survive. For five years, the Hathians kept their world safe by hiding behind a façade, posing as subservient peasants and pretending all the wealth and knowledge of Hathe has vanished. Then came the time for Hathe to fight back, and for the Terrans to learn how wrong they were.
Now the war is over.
Hamon Radcliff was once head of security for the Terran forces. His wife, Marthe an Castre, belonged to the Hathian resistance. Surviving the peace was always going to be tough for lovers caught on opposite sides. Both did whatever was needed to protect their home worlds, and those actions have consequences. The end of the war doesn’t take away all the bitterness, and when that anger it turns its glare on Marthe and Hamon, peace time becomes downright dangerous.
