Resumen
Harry Dresden, Chicagos only professional wizard, is about to have a very bad day. As Winter Knight to the Queen of Air and Darkness, Harry never knows what the scheming Mab might want him to do. Usually, its something awful.
This time, its worse than that. Mabs involved Harry in a smash-and-grab heist run by one of his most despised enemies, to recover the literal Holy Grail from the vaults of the greatest treasure horde in the world - which belongs to the one and only Hades, Lord of the Underworld.
Dresdens always been tricky, but hes going to have to up his backstabbing game to survive this mess - assuming his own allies dont end up killing him before his enemies get the chance . . .
