Definitely a story within a story filled with suspenseful moments and the angst of dysfunctional families and teenage love. An immortal born because of his parent's mistake, Jack, is not allowed to love or he will die when his heart breaks. Despite his impending doom, Kate and Jack are drawn to each other and refuse to be denied... until she meets Sebastian. Add finding lost family members, pregnancy with a mystery dad, and the possibility of turning immortal and it all leads up to the next book in the series. A stand-alone novel it is not but well worth reading the rest of the series.
