Shimmer

Logan Walker has a gift. He senses supernatural trouble before it happens. But when his special talent predicts hell on earth, he knows his gift has become a nightmare for him and his unusual family. Possessing various paranormal abilities, the Walkers have, through generations spanning thousands of years, protected the human race from supernatural predators. These creatures enter our world through dimensional rifts and must be defeated or returned to their world before wreaking havoc in our own. But the Walkers have suffered a long war of attrition and their numbers have dwindled. They are at their weakest when our world faces its greatest threat. And time is running out.
