The bridge to the other side has finally collapsed, and the vampires and werewolves are at war. Bonnie Bennett is the anchor to both worlds, and her ex, Jeremy Gilbert, has been ordered to kill her since he's a vampire hunter. There's only one problem: they're still in love with each other. But neither will admit it. Damon Salvatore is fighting his ever-growing feelings for beautiful human Elena Gilbert, just as Elena is falling for his brother, Stefan. But Stefan has a few dark secrets of his own, and Elena is torn between two brothers. Only she's really the one with the bloodstained hands. Caroline Forbes won't wait a moment longer to kill Elena, her brother, and take the werewolves down with her. But she needs a spell. And the only witch in town is currently half-dead and very wanted, as well as the anchor. So Caroline needs someone else. Preferably someone with a taste for revenge. Tyler Lockwood is trying to keep the hybrids neutral, but as their fate grows darker and darker, he's tempted to take off the chains and let the wild dogs out. Kidnapping a human wasn't part of the equation, but neither was being half vampire and half werewolf. And while being trapped with sarcastic human Matt may want to make him rip someone's head off, he reckons that all that rage will come in handy. All hell's about to break loose.
