I recently finished "Black House" by Stephen King and Peter Straub. It's a sequel to their work "The Talisman". The child hero of that book, Jack Sawyer, is 20-22 years older and is a retired (his family was wealthy) former LAPD cop who has moved to Wisconsin.

But there's a serial child killer on the loose who proves to have links to places and experiences Jack has forgotten about. "Black House" also has been written to bring in links to King's "Dark Tower" series.

It was fun trying to pick out just who wrote what. The story was very hard core horror though and not for faint of heart.

"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
