Book excerpt: Remember when Abbott and Costello met Frankenstein, or when Freddy met Jason? Remember when all the monsters met for a mad, mad party, or when Scooby Doo met Mr. Hyde? Remember when Hellboy punched out the Great Old Ones or when Sherlock Holmes staked Dracula? Or, perhaps, you're younger and you can still vividly recall Buffy taking on Xenomorphs, or the Ghostbusters sending Cthulhu back to the watery depths, or Joss Whedon's Cabin in the Woods. You may recall when the Planetary Foundation dug into the secret history of giant ants and 50 foot tall women; or, possibly, the alternate universe where Dracula ruled England. Much harder to recall are the days when Carnacki the Ghost-Finder faced down The House on the Borderland, or the mosaic made from Stephen King's novels. You may have forgotten. But take a deep breath. Robert E. Wronski Jr. remembers. From his secret library of notes, he brings you a book dedicated to chronicling these stories: recording the myriad easter-eggs and hints that tie together modern horror and prove the universe to be nothing more than a thing of terror. The Horror Crossover Encyclopedia is a reference guide of fictional crossovers within the horror genre, using a "six degrees" methodology. Settle deep in your coffin, fill your pipe with tana leaves, and enjoy.
