Jasmine King, widowed wife of a war veteran, is a professional ecologist and broker. Her neighbor, pretty, white, Tabitha Mason still has her husband, but he treats her like a trophy wife. The unlikely pair become fast friends, a bond they'll need to help them through the danger on their doorsteps.
Bradley and Benjamin Johnson have a private investigation firm called Johnson & Associates. But they're not brothers, hell, they're not even the same race. When the mysterious Collector sends them to retrieve a tainted artifact, they learn that love crosses even more boundaries than magic.
