Midnight Kiss Vol 1 TPB (2007)

In a shattered multiworld where every dream is one world's reality, Matthew Sable and Nightmare De'Lacy try to keep the balance, facing Angels and Demons, Supernatural Hitmen, Tin Men and Aligator Kings at every turn. But when a 'rational' -- a normal human, unaware of the war within is brought into the fight, Matt and Nightmare must protect him before he discovers what he really is -- or what they really are ...
Believe in faeries -- if you don't, they'll kill you.
