I've long been a fan of both HP Lovecraft's horror stories and of Golden Age superhero comics, so here's a combination of both -- Ken Hite's Adventures Into Darkness: H.P. Lovecraft's Superheroic Horror!

The book is meant for both Hero Games and Mutants & Masterminds, and presents itself as being from an alternate reality where Lovecraft survives his 1937 illness and, to cover the bills and with some encouragement from real-life HPL associates/friends Robert H. Barlow and Julius Schwartz, starts writing comic book adaptations of his novels and then writing directly for the Nedor superhero lines. Including adapting both Randolph 'the Dream Master' Carter and Nodens along with several of the villains and monsters from his print stories into superhero comic form. Normally this would just consist of some game write-ups for various HPL monsters and characters, but Mister Hite goes the extra mile by presenting a fake bibliography focusing on Lovecraft's post-1937 fiction career, including the films he made out of 'Charles Dexter Ward' and 'Shadow over Innsmouth' after moving to Hollywood and working with Val Lewton, Orson Welles, and Jacques Tourneur. He even has a price list from the Comic Buyer's Guide covering HPL's work for Dream Master Comics and Adventures Into Darkness, the latter a real-life Nedor horror anthology comic.

The listed characters are mainly Nedor comic heroes like Doc Strange and Mystico and more, though with all of them given a Lovecraftian twist. He also has write-ups for a dozen villains, two of them original Nedor characters and the rest adapted Lovecraft villains. My favorite is probably the Devilfish, a crime boss from Innsmouth who is basically a Deep One hybrid as a Dick Tracy villain.

It's also got some brief essays in the back on how to combine both HPL's 'cosmic indifferentism' and his more light-hearted 'Dunsanian' works with Golden Age superheroics. It's definitely an odd little book and not for everyone but if you like the Golden Age of comics as much as Lovecraft's stories I think you'll enjoy this.
