Awakening. The Architect's Guardian, #1

Armando Medina suffered a tragic loss at the hands of some Nitelvosa, supernatural beings who control his world. For decades, he's been unable to forget the horrific night when his life changed. Izdahl Amasi, a member of a prominent Nitelvosa family, had briefly dated Armando. He'd hoped for much more, but Armando's trauma drove a painful wedge between them. With each passing day, Izdahl's heart grew heavier, as he thought of what could have been. Now, Armando and Izdahl find themselves connected in unexpected ways.
Despite how much Armando tries to avoid the truth of their attraction, he's drawn to Izdahl. Looming over them are events from Armando's youth and the mystery of who's responsible for his anguish. Can Armando open his heart and trust Izdahl? Or will Izdahl stop believing they have a chance?
