A Madness Of Angels by Kate Griffin

When a man is tired of London he is tired of life; for there is in London all that life can afford - Samuel Johnson
In fact, Dr Johnson was only half right. There is in London much more than life - there is power. It ebbs and flows with the rhythms of the city, makes runes from the alignments of ancient streets and hums with the rattle of trains and buses; it waxes and wanes with the patterns of the business day. It is a new kind of magic: urban magic.
Enter a London where magicians ride the Last Train, implore favours of The Beggar King and interpret the insane wisdom of The Bag Lady. Enter a London where beings of power soar with the pigeons and scrabble with the rats, and seek insight in the half-whispered madness of the blue electric angels. Enter the London of Matthew Swift, where rival sorcerers, hidden in plain sight, do battle for the very soul of the city . . .
