Matia Evans has it all, except for one thing: she can't see color. With an adopted family who loves her, a company she helps her father run, and more prospects than she knows what to do with, she's in no place to complain that her world is limited to shades of gray, black, and white. Her inability to perceive color isn't the only strange thing about her: all souls have shadows, and she can see them. Unfortunately, there are humans who are worse than monsters. Worse, there are real monsters in the world, and they view humans as prey or as mates. If Matia doesn't want to become a victim, a pawn, or a trophy bride of the supernatural, she must use every bit of her strength and cunning. Her freedom and survival depend on embracing the darkest parts of her soul, but if she does, she risks becoming the newest-and most dangerous-monster of all.
