Gin declared war on Mab Monroe in Venom. Since then she has attacked Mab's organization by killing her enforcers. With other mobsters getting bolder and thinking about making a move against her, Mab needs to get Gin and finish her off once and for all. She hires Electra an elemental assassin with the power to control (you guessed it) electricity, to hunt down Gin and kill her along with her sister, and a bunch of other people who have dared to step on her toes.There are going to be 10 books in this series. I tend to lose patience with a series after 3 books, but this is book 4 and so far they aren't losing their luster. I don't know if I have 10 books in me, but I'm prepared to commit to another two.
