"Joe Bodenland, a 21st century American, passes through a timeslip and finds himself with Byron and Shelley in the famous villa on the shore of Lake Geneva. More fantastically, he finds himself face to face with a real Frankenstein, a doppelgänger inhabiting a complex world where fact and fiction may as easily have congress as Bodenland himself manages to make love to Mary Shelley"-- http://www.centipedepress.com/sf/frankensteinunbound.html (as viewed on December 1, 2016).
