Bonnie Bennett was always willing to die for the people she loved. This time, she actually does. After sacrificing herself during a deadly confrontation with Klaus, Bonnie awakens with vampire blood in her veins, an unbearable hunger, and the magic she should have lost still burning inside her. She has become something nature never intended-a vampire with the full power of a Bennett witch. Elijah claims he saved her because her life was worth more than another sacrifice. Klaus sees her transformation as an impossible mystery he is determined to possess. As both Original brothers are drawn deeper into her life, Bonnie must master her bloodlust, uncover the truth about her ancestors, and decide who she can trust. But the greatest battle will not be against Klaus, Elijah, or the darkness inside her. It will be learning to choose herself.
