Reality, tiny and fragile, is cut off from the sea of chaos and nightmares that surrounds it by seven Gates. One of them is open-and has been since the Stone Age. Through that opening, strange creatures and energies slip through. Some are malevolent. None are harmless. And all of them must be kept a secret.
Every hidden magical world needs a shadowy clean-up crew. Adrian Somer is a Gatekeeper, sworn to protect the cosmic Gates, to defend reality from the unknown entities that exist beyond them, and to help those whose lives are affected by magic.
