A COLD ONE introduces conjuration mage, Esme, who works as a bartender and moonlights as an enforcer for the Assembly, who are basically the magic police. Between the two Esme has her hands full balancing her friends, dating life, her secrets, and her efforts to only use her magic for good. We also very briefly meet Miles who manages to catch Esme's eye even though they haven't interacted yet. This was just a quick set up for the REVIVAL OF THE FALL series but I'm curious to see what happens next for Esme.
