Green Witch - Dragon Wars, #4

Cyan Parrish is a healer, but those of narrow minds and suspicious thoughts have called her a Witch. Now someone wants her so-called powers for himself and he's willing to kill for it. Death to the Green Witch. That's the message left in the smoking ruins that was once the home of the woman Sutter loved. His only hope of saving her is to put his trust in one of the enemy, and travel across an apocalyptic wasteland toward a fabled city ruled by a madman.
This exciting adventure is the fourth in a mesmerizing and addictive post-apocalyptic romance series.
