Empty Colors

"And when I saw you."
I could see his throat bobbing as he swallowed harshly. I was breaking him. I was taking everything.

Wolves naturally only have red and blue receptors in their eyes. They cannot see anything but variations of those two colors, and therefore they are partially colorblind.
Werewolves are the same. However, once they have imprinted on their true mate, they are able to see fully, to see every color in existence, like a human.
When a girl who didn't even know werewolves existed, Malia Thomas, is imprinted on by the alpha of a local pack, she doesn't even know it. Not until she begins to hear strange, mournful howls at night, and a boy in her college physics course finally talks to her.
She's become a target for any wolf who rivaled the alpha who has imprinted, Allan Greg, and she doesn't even know it.
And then an injured, dark brown wolf stumbles onto the patio of her apartment, and she realizes that werewolves may not be as fictional as she thought they were.
