Twentysomething bartender Jason Bishop's world is shattered when his estranged father apparently commits suicide, but the greater shock comes when he learns his father was a secret agent in the employ of the Invisible Hand, an ancient society of spies wielding magic in a centuries-spanning war. Now the Golden Dawn, the shadowy cabal of witches and warlocks responsible for his father's murder and the death of his mother years before, have Jason in their sights. His survival will depend on his mastering his own dormant magic abilities--provided he makes it through the training.
