EDGE OF SPIDER-VERSE #1

Doctor Strange is a busy man - sometimes, it seems like the busiest man. But that man has a best friend. So when there's something strange haunting the Sanctum Sanctorum, who can we turn to? Why, BATS THE GHOST DOG, of course! But can Bats solve the mystery on his own, or is this good dog in over his head?
