The Scarlet Deep: Elemental World Book Four

Some bonds don't break. They just wait.

A poison is moving through the North Atlantic, corrupting the human blood supply and pushing immortals to the edge of madness. Patrick Murphy —Dublin's most powerful vampire leader— has been fighting to keep Elixir out of his city. And he’s been losing. Now he's been called to London, where the most influential figures in the immortal world are gathered to find the traitor responsible for it all.

Anne withdrew from that world a century ago. After Murphy, she needed the quiet. She found purpose instead, tending to immortals who needed a listening ear. But Elixir has reached even her rural refuge, and with the blood supply tainted and her bloodlust rising, the people closest to her are no longer safe.

London forces them together again. So does the investigation, the danger, and the slow-building pull of something neither of them has managed to bury. Behind closed doors and careful diplomacy, old hunger stirs. Their past never really ended… it just went underground.

As an new threat moves against the Elemental World, Murphy and Anne will have to choose between the safety of distance and the truth of what they are to each other.

Elemental World, Book 3. Best read after Blood and Sand, though it stands on its own for new readers.
