In this hilarious send-up of Lovecraftian horror and steampunk adventure, President Abraham Lincoln's top spy is a bodyless head known only as Screw-On Head.

When arch-fiend Emperor Zombie steals an artifact that will enable him to threaten all life on Earth, the task of stopping him is assigned to Screw-on Head. Fortunately, Screw-On Head is not alone on this perilous quest. He is aided by his multitalented manservant, Mr. Groin, and by his talking canine cohort, Mr. Dog.

Can this unorthodox trio stop Emperor Zombie in time? Does Screw-On Head have a body awesome enough to stop the horrors that have been unleashed? Where can we get a talking dog?

All these questions (O.K., maybe not that last one) are answered by the thrilling tale of The Amazing Screw-On Head!
