If you do it well, lying is every bit as effective as magic.
Conrad Brent has no innate magic, so he bluffs a lot and uses a myriad of magical items to protect Brooklyn from monsters and arcane threats. As a member of the Watch, the group that protects the mundane humans from such dangers, he risks his life on a regular basis. Sometimes twice before lunch. Sometimes during lunch, when he dares order his food from a street cart.
After regaining his position in the Watch which he’d temporarily lost due to the machinations of a variety of evil-doers, Conrad doesn’t want to take any risks he doesn’t have to. But now his boss is missing, there’s a totalitarian new regime in City Hall oppressing all magic users, and the mayor has aligned himself with a diabolical villain.
In order to save the day, Conrad must team up with a recovering necromancer to mediate a dispute between two ancient enemy factions, solve a mystery of a warded house adjacent to a cemetery, and stand with his friends against tyranny.
That is, if the interdimensional fae assassins don’t get him first.
