When Miriam met John, in 18th century France, she told him that he would live forever. As a half-human, half-vampire hybrid, he survived two centuries at her side, drinking the blood of their victims.
But during the 1980s, in New York City, John discovers that Miriam didn't tell him the whole truth. When he begins aging the process is rapid. From young man to old man in a matter of hours.
It finally occurs to him to ask, if he cannot die, then what happened to her previous lovers and companions? She grieves for them. She misses them. They too once aged rapidly, as he's doing now. So where are they?
The answer is horrific. More horrific the more you ponder it. Miriam weeps for them all.
A solution may lie in 20th century medicine. Dr Sarah Roberts has become a semi-celebrity for her work on blood and aging. Plastered all over the television and publishing books on the subject, there is ample opportunity for her to catch the attention of both Miriam and John.
Can she save John in time? Or will Miriam drag her more fully into their world instead? Because Miriam cannot be alone. She's a vampire who was born when Egypt was still young. She'd get lonely, if she had to go on without a companion, whatever the cost.
