The Vampire Girl in London

In The Vampire Girl Next Door, Mark fell in love with Sylvia,
the beautiful, but quirky girl next door, not realizing that she was
a vampire who killed his last neighbor.
Now, in The Vampire Girl in London, they fly from Mark’s
San Francisco to Sylvia’s London. They tangle with terrorists,
are shadowed by a CIA agent, and are pursued by a vampire-hunting cult.
Even more challenging, they must cope with living in a mansion full
of Sylvia’s vampire friends—some of whom she can’t really trust.
And Mark still has to deal with Sylvia’s sexual hijinks.
Will Mark and Sylvia’s love be enough to survive it all?
