Alex Locke is a reformed ex-con forced into London's criminal underworld
for one more job.
He agrees to steal a priceless artefact--a human heart carved from the
blackest obsidian--but when the burglary goes horribly wrong, Alex is
plunged into the nightmarish world of the Wolves of London, unearthly
assassins who will stop at nothing to reclaim the heart.
As he races to unlock the secrets of the mysterious object, Alex must
learn to wield its dark power--or be destroyed by it.
