Sun, Moon & Shadow by Lorin Coffler:
 
Orphaned and outcast, Nova leads a solitary life, but the eve of her twenty-fifth birthday brings a stranger to her doorstep.

The mysterious visitor, Callan, reveals that Nova is no mortal, but one of the mythical Fae folk, hidden among the humans since birth. With the glamour concealing her true form set to vanish within hours, Nova must place her trust in him as he escorts her to the world of the Fae.

While Nova adjusts to her new reality in which looks can be deceiving, her carefully constructed walls begin to crumble as her attraction to Callan blooms. When the truth of her identity is revealed, she must learn to rely on others as she uncovers the legacy of the blood flowing in her veins.

Callan’s task was simple: retrieve the female and deliver her to the Fae Realm of Aemoria. But after centuries of drifting through life, like a ship without a mooring, he finds himself drawn to her. His desire to protect Nova forces him to confront a past long-buried and decide how much he is willing to risk to keep her safe.

With Aemoria threatened by a gathering darkness, a shadow that has seeped into Nova’s dreams since her arrival, both must face their own demons to protect those they hold dear.

Painful pasts Futures uncertain Will their undeniable bond be their strength or their ruin?
