He's creating his own gang that will replace everyone - including Max.
Max is heartbroken over losing Fang, her soulmate, her closest friend. But with Dylan ready and willing to fight by her side, she can no longer deny that his incredible intensity draws her in.
Max, Dylan, and the rest of their friends must soon join with Fang and his new gang for an explosive showdown in Paris. It's unlike anything you've ever imagined ...or read.
