Bound by the Ashmoon Curse. The Ashmoon Covenant, #1

He was cursed to destroy his fated mate. She may be the only woman powerful enough to save him. Elara has spent her life believing she alone controls her future. Then a brutal attack awakens a power buried inside her-and brings her face-to-face with Averic, the dangerously compelling stranger whose soul seems to recognize hers. Averic has waited centuries for the woman bound to him by the Ashmoon Covenant.
He never expected her to be the one person his curse demands he destroy. Their bond should make them allies. Instead, every touch strengthens the ancient magic poisoning Averic's blood, pushing him closer to becoming the monster Elara has every reason to fear. Yet walking away is no longer an option. A ruthless enemy has begun hunting the witnesses connected to their bond, and Elara is at the center of a plan that has been unfolding for generations.
Forced together by danger and divided by secrets, Elara and Averic must decide whether their connection is true fate-or another weapon created to control them. Because the Ashmoon curse was never meant merely to kill them. It was designed to make their love destroy everyone around them. Bound by the Ashmoon Curse is the first book in The Ashmoon Covenant, an emotionally intense paranormal romance series filled with fated mates, ancient magic, dangerous secrets, supernatural intrigue, betrayal, sacrifice, and a powerful love capable of defying destiny.
