Vampire, Interrupted carries on directly after the previous book, Vampires Are Forever, and in fact some of the events in this book relate to those in the previous. Vampires Are Forever featured Thomas Argeneau, sent to look for his aunt Marguerite. She has gone missing while working as a detective to find the mother of Christian Notte, who hired her. In Vampire, Interrupted, we see events from Marguerite's point of view as she travels to England and from London to York in search of the story of Christian's past.

This reader had felt that the Argeneau series was getting a little tired and formulaic, basically rehashing the same plot devices (woman is turned into vampire by Argeneau man, has to learn to live with the new life, decides she loves the hero). Vampire, Interrupted is a rather different book, and this is a great mark in its favor. For once, both hero and heroine are already vampires, are in fact old vampires with children and long histories. In this story, Marguerite finds herself under attack from a mystery assailant as she, along with mortal private detective Tiny, tries to follow historical clues to Christian Notte's origins. She knows already that Christian's father, Julius, won't tell him about his mother. Instead, Julius has managed to frighten off every previous detective from the hunt, and sure enough Julius appears on the scene in London. Yet things are rather different, and he doesn't try to prevent Marguerite and Tiny's searching; indeed, he goes with them as they travel to York to try to find out more.

It soon becomes clear that events in Marguerite's past may contain the answer to some of her questions, as well as causing her to mistrust Julius when she finds herself drawn to him. There are some unexpected plot directions in this book that work really well - even the 'baddie' is a surprise yet very plausible. The story of two older people trying to put aside their cumulative life experiences to learn to trust each other is very well written, and the conclusion wraps up nicely. This is definitely one of the better stories in this series and undoubtedly will appeal to Lynsay Sands' fans.
