Daemons Are Forever — Simon R. Green

New York Times bestselling author Simon R. Green returns with an all-new urban
fantasy mystery featuring the first name in supernatural action and adventure...

BOND. SHAMAN BOND.

Actually, the name's Drood, Eddie Drood. For centuries, the Droods have been fighting the monsters in the shadows so that the rest of you lot can go about your everyday lives. These days, I'm the head of the family.

Because I'm the head of the family, it's fallen to me to deal with a bit of a mess left over from World War II. Seems that back then the Droods made a pact with a bunch of demons known as the Loathly Ones to fight some really nasty buggers called up by the Nazis. Once the war was over, we couldn't get rid of them. Now they're calling their masters to invade and destroy our world...and we Droods are the last, best hope of stopping them.

I'd say that the world is in a major lot of trouble.
