Prey

When a Russian criminal is torn to pieces by a powerful animal, Moscow cop Lev Dasaev follows the trail to the U.S. – and to the lair of a murderous madman called Wheeler Burns.
Ruth Templeton will stop at nothing to destroy Laura Greenacre, the mysterious woman who was last seen disappearing into the tunnels beneath London – and her quest leads her to America.

The Templetons and the Greenacres will go to war one last time. And as in London eight years previously, werewolves will be unleashed – this time on the streets of New York.
Bloodlust and vengeance unite Ruth and Burns as they conspire to annihilate Lev and Laura – and the ultimate hunter becomes the ultimate prey...

Prey is the sequel to Thomas Emson's first novel Maneater, which featured Laura Greenacre, described by one critic as "gory and gorgeous".
