Aerenden: The Gildonae Alliance (Aerenden Series #2)

Several months after Meaghan's return to Ærenden, the kingdom's war has taken a turn for the worse. The Mardróch army hunts the new King and Queen, destroying villages in its wake. And Meaghan and Nick, training for battle in a remote section of wilderness, are far from safe. Danger hides in shadows and behind innocent faces. Allies become foes. Each day is a fight to survive. But in the end, only one threat matters. And it's a threat they never see coming.
