Most Goosebumps books feature a villain of R.L. Stine's own creation, but Frankenstein's Dog is a bit different, and I like that. When twelve-year-old Kat Parker is sent by herself to a faraway country to visit her Uncle Victor Frankenstein (great-grandson of the notorious doctor who brought Frankenstein's monster to life), she has some idea that the vacation won't be a normal one. She's enjoyed spending time with her scientist uncle whenever he's visited her family, but Kat is a little spooked by the idea of staying alone with him in a castle-like manor built several hundred years ago. The villagers are on edge and don't exactly greet Kat with warmth and cordiality, but Uncle Victor tells her not to worry. The people may still hold his great-grandfather's reanimation experimentations against him, but Kat is perfectly safe as long as she doesn't wander far from the house.
Like the original Doctor Frankenstein, Uncle Victor is interested in animating lifeless matter, but his expertise is artificial intelligence, particularly advanced robotics. Victor has invented state-of-the art robot assistants to help him in the laboratory, robots that look, sound, and feel exactly like humans. Kat wouldn't even know that Victor's main assistant, a robot named Frank made up to look like a young man, isn't human if Victor hadn't told her. But cutting-edge artificial intelligence can be difficult to keep from getting out of hand, and as Kat explores her uncle's mansion with a local boy her age named Robby, she finds things that cause her to worry that Victor may not be as in control of his experiments as he wants her to believe. Could his robots be on the brink of breaking free from their creator's control and terrorizing the village as Frankenstein's monster did three generations ago? With robots all around that are nearly indistinguishable from people, it becomes challenging for Kat to discern who is human and who is merely masquerading as such. Will she ever figure out who's who in Doctor Frankenstein's modern house of horrors?
Frankenstein's Dog is a good concept, though I wonder why it was given that title. I'd give the book one and a half stars, and if the ending were more clear and concise, I probably would have rounded up to two. I like that R.L. Stine continued innovating after so many years writing for kids, creating new books to please young readers who prefer their stories with some zest. Like most Goosebumps novels, Frankenstein's Dog has that zest, and I had fun with it. Nothing hits the spot for juvenile horror literature like a Goosebumps book.
