Wolves of London

"Alex Locke is a reformed ex-con, forced back into London's criminal underworld for one more job. He agrees to steal a priceless artifact--a human heart card from 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 raced to unlock the secrets of the mysterious object, Alex must learn to wield its dark power--or be destroyed by it." -- Page [4] cover.
