The Book of Enoch: Lucky 7

The siblings of the Family Enoch are named after the seven Archangels who sit in the presence of God. Anyone who knows them finds this ironic, as the seven are all equal partners in the most successful outlaw Motorcycle Club in Montana. Drugs, Protection, Trafficking in stolen goods, and Gun-running are all in a day's work. That is until the dark, moonless winter night when they're visited by their namesakes on the Interstate, riding home after closing their favorite watering hole.
Each has their reason for deciding to help the seven visitors on their mission. Now, they must find and help the seven Asgardians sent to Earth with Dead or Alive warrants from the Council of the Nine Realms for Loki and his band of six giant demons. Loki and crew have destroyed Midgard and its 7 billion residents, and the Earth is next. The only real problem is; the siblings have to allow the Archangels to cohabitate within their minds in order for them to remain in an Earthly plane of existence.
That and the Asgardians want nothing to do with them. They have seven days to find the demons and the world bomb they intend to use; somewhere in the Upper Cascade Mountains of Washington State. Otherwise, Rafael will go to the Sacred Mound in Jerusalem and sound the trumpet signaling the End of Days.
