'Lost' is a short story that involves my favorite Immortal Couple, Torvald and Victoria Svensen. The story takes place about a year after chapter 8 of A Voice From The Past
and it does include a few others from the other story line. There is a few 'Guest Appearances' that I am sure you will enjoy.
This is a completed works that is being posted on the The Raccoon's Bookshelf
and can be read over there.
