Simon. Something frightful has happened to Jamie. Please come . . .

When James Asher is found unconscious in the cemetery of the Church of St. Clare Pieds-Nus with multiple puncture-wounds in his throat and arms, his wife, Lydia, knows of only one person to call: the vampire Don Simon Ysidro. Old friend and old adversary, he is the only one who can help Lydia protect her unconscious, fevered husband from the vampires of Paris.

Why James has been attacked - and why he was called to Paris in the first place - Lydia has no idea. But she knows that she must find out, and quickly. For with James wavering between life and death, and war descending on the world, their slim chance of saving themselves from the vampires grows slimmer with each passing day . . .
