Traitors Among Dragons: Maiden to the Dragon #4 (Alpha Dragon Shifter Romance) - Maiden to the Dragon, #4

Miriam and Xander's halcyon days of rest along the shores of Beriadan Lake in Alexandria come to a quick end when the pleas of another dragon lord lead them to the blackened Heavy Mountains.  Lord Herod demands their attentions on a pressing matter, and what they find is a pot of trouble boiling over with ancient blood feuds, uneasy alliances, and old stories of treacherous Maidens. Trouble comes along the winds of a storm, and Miriam finds herself in the middle of it.
 Now she must prove her innocence against a hefty charge, or face the fatal consequences.  The trail leads them to the Coven Caves where witches cast more than their shadows on the walls.  One life-attempt after another shows they're on the right trail, but only if they can stay one step ahead of their mysterious foes.  Otherwise, the mountains will be their final adventure. The Maiden to the Dragon books are part of a dragon shifter romance series set in a fantastical world that mirrors our own.
