The Book of Dead Days

The days between Christmas and New Year's Eve are dead days, when spirits roam and magic shifts restlessly just beneath the surface of our lives. A lot can happen in the dead days. A magician called Valerian must save his own life within those few days, or pay the price for the pact he made with evil so many years ago. But alchemy and sorcery are no match for the demonic power pursuing him. Helping Valerian is his servant, Boy, a child with no name and no past. The quick-witted orphan girl Willow accompanies them as they dig in death fields at midnight and are swept into the sprawling blackness of a subterranean city on a journey from which there is no escape.
