This is a continuation of "What Now" In the last book, Hope brought Klaus back from the dead when he reconnected with Caroline and they bonded with each other's friends and family. Kai returned and killed Ric. He also killed Lizzie by turning her into a vampire which made Josie the twin that wins the merge by forfeit. Klaus and Caroline killed Kai. The book ended with Klaus and Caroline getting engaged. This book is going to lean more into the life of the blended family with Klaus and Caroline navigating spending the rest of their life together, but that will not be without its challenges.
