The Return by David A. Riley
It was never going to be easy to return for one last look at the streets where he spent his childhood years. Even knowing this, Gary still felt he had to make the effort, just this once, to see if they were really as bad as he remembered. In a few months demolition was due to start on Grudge End…
When Gary Morgan travels north to lie low after a gangland shooting in London, a childhood friend is violently maimed within hours of his arrival. Decades after escaping the blight of his hometown, he finds himself ensnared in a place he hates more than any other.
Feuding families, bloodthirsty syndicates, and hostile forces older than mankind all play a role in the escalating chaos surrounding Gary Morgan. Now he must unravel the mysteries of Grudge End and his own past or meet his doom in the grip of an ancient, unimaginable evil.
