The Pendragon Tea Rooms - Melody R. Green

Maggie finds herself travelling to Stonehenge and Glastonbury at the request of Pendragon, Dragon High King of Britannia, to help him save the Dragon Queen of Avalon from the encroaching dark forces.
But Maggie is without her usual ally, Archangel Michael and finds herself at the crossroads between Spirit and the nefarious mundane realm of drug and sex trafficking.
To add to her discomfort she is romantically pursued by the not quite "honourable" Mac. How will she reconcile her need to work for the light with her love of a shadowy Scottish biker?
And where is Archangel Michael, when she needs him? Even Archdemon Phineas, the Archangel of Chaos seems to have disappeared. it's all rather odd and Maggie feels as though she's floundering on her own in this summer adventure.
