Book 3 in Erika Hammerschmidt's "If the World Ended" series. A grandpa attacks Santa Claus. A palindrome artist redefines fiction. A time traveler disappears. A telepathic vampire tries to change humanity, and a genie goes atomic. From deep and dark to lighthearted and zany, these speculative fiction stories explore the depths of unique and outlandish minds, and the strange forms of logic that can lurk in them. (Adapted from the 2013 short story collection "If the World Ended, Would I Notice?")
