The Sleep That Rescues — C.J. Henderson

Private investigator Teddy London, who has stood firm against vampires, werewolves, and terrors from beyond without flinching, now faces not only an unimaginable god-horror of unlimited power but also the consequences of his own reckless ego. Acting without thinking, he inadvertently opens the doorway of the dreamplane to a beautiful cat burglar, giving her access to the secrets of the universe. Now, the balance of all time and space has been thrown into chaos, and Teddy will need more than a gun named Betty and a blade named Veronica to save his own skin, let alone the entire world.
