Unforgiving Dreams by Jessamyn Kingley

Fifteen thousand years ago, the Fae realms crumbled. A decade ago, Noble Protector Drekkoril D’Vaire of the Light Fae woke after spending many millennia in a dreamless sleep. Upon waking, he discovered his people no longer exist. A goddess revered by the Fae had changed them into elves and sprites with no memory of the past. Thanks to a wonderful, supportive family, Drekkoril healed from the ordeal. Now he wants to find the other half of his soul.
Valiant Defender Daravius of the Dark Fae wanders from place to place, trying to put food in the bellies of his tiny family. With little knowledge of any language still spoken and no resources, Daravius’s existence is meager. Each night, he uses a spell to travel to the destroyed realm that once carved deep scars into his soul; night after night, he must relive the horror. Although Daravius wants more for his loved ones, he is lost.
Expert trackers locate Daravius and his family, and they bring the trio to D’Vaire for sanctuary. Within minutes of their arrival, Daravius and Drekkoril learn they are mates. Drekkoril rejoices and yearns for a future together, but Daravius is terrified and desperate to avoid uniting their souls. Only Fate knows which man will get his wish.
