Claimed at the Blood Eclipse. The Ashmoon Covenant, #3

The Blood Eclipse has risen, and every possible future is collapsing into one. Elara Vale and Averic Moonclaw survived the curse that tried to weaponize their bond and the Crown that turned memory into obedience. They chose each other without destiny's permission. Now an ancient power intends to make that choice permanent-and turn love itself into ownership. Rhyven Korr has found the one future in which he cannot lose.
As the eclipse bleeds across the sky, names vanish, bonds harden, and every road begins leading toward the same ending: Averic enthroned, Elara claimed, and a world where no one can choose differently again. Their only hope lies in the oldest Ashmoon ritual-a claiming powerful enough to rewrite the law of every supernatural bond. But the ritual was designed to create a master and the one who must obey.
To defeat Rhyven, Elara and Averic must enter the claim willingly, trust one another with the power to destroy them, and transform a ceremony of possession into something the old rulers never imagined: a bond that survives only while both people keep choosing it. If they fail, the Blood Eclipse will seal their fate forever. If they succeed, they may free every future except their own. Claimed at the Blood Eclipse is the epic final book in The Ashmoon Covenant, a dark, emotionally intense werewolf romantasy trilogy featuring chosen mates, a powerful heroine, a tormented Alpha, dangerous bond magic, political intrigue, betrayal and redemption, found family, high-stakes sacrifice, and a hard-won happily ever after.
The trilogy should be read in order.
