One awkward summoning. One chance at redemption.Kei can't believe his last ditch effort at stopping what could very well be the coming apocalypse has failed before it ever started. And all because he messed up one spell.From the moment the angelic man looks up at him from the within the sigil inscribed on the ground, Kei knows he's in trouble. Blue eyes, smooth skin, and a body so perfect...it's Heavenly. Getting involved with someone pure-no matter the physical pull-is nothing short of sinful. He just wished his soul cared enough to stay away.But becoming lovers is the least of their worries. Darkness looms on the horizon, and if they can't find a way to stop it before it takes hold, humanity won't be the only thing that falls from grace.
