Graceless (слэш)

Set post-season 9, Metatron has taken Gabriel’s grace. Cast out of Heaven, weak and helpless, Gabriel calls the Winchesters.
Sam finds himself with a grumpy, awkward ex-angel who has no idea how to be human. As they hunt for Gabriel’s grace, Sam is drawn to the archangel despite his better judgment.
In the middle of the search, Sam is hit with a deadly spell meant for Gabriel, and now it’s a race against time to find the cure and keep Sam alive.
And as if things weren’t complicated enough, Sam thinks he might be falling in love.
