By trope I mean a popular/familiar plot element (e.g. demonic possession is a horror trope, a prophecy is a fantasy trope) or a popular/familiar type of character (e.g. in detective novels, the maverick officer who is willing to break the law to catch the criminal). So, what are your favourite tropes? What will you see in a blurb that would make you buy the book or make you put the book back on the shelf? Mine are: Horror - Demonic possession, curses, creepy children, characters isolated in the middle of nowhere with an unknown killer among them, ouija boards, and murderous freaks (e.g. The Hills Have Eyes). I generally avoid haunted houses, and supernatural creatures like werewolves, zombies, and vampires. Sci-fi - I love mysterious pandemics, cryptids, genetic engineering gone wrong, alien invasions, and finding weird things on other planets. I avoid anything set in space, anything dystopian and, again, anything with werewolves, zombies, or vampires. Crime/thriller - Corpses suggesting occult deaths (like weird symbols etched into the skin) or ritualistic killings, novels focusing on forensic pathology rather than pure detective word (e.g. Rizzoli and Isles), mistaken identity or identity switching. Not a fan of military, political intrigue, or spies; nothing fuelled by testosterone. Romance - I like tortured heroes, enemies-to-lovers, forced proximity, and fake relationships becoming real. Do not like alpha males, sports romance, or conflict based on easily-resolved misunderstandings.
