A vampire book I got in a book package I bought from one Facebook flea market. I've tried but have not managed to read it so it can continue its travels.

The book is a story of eternally living Miriam Blaylock, whose problem is that her human partners grow old and die. Now her husband John is slowly withering away and Miriam sets out in search of a new partner. Scientist Sarah Roberts looks promising because she may have discovered the secret to immortality, but two people stand between Miriam and Sarah: Miriam's still alive husband and Doctor Tom Haver.
