Gaslamp Fantasy (aka Gaslight Fantasy): This is a subgenre of Historical Fiction that is generally (but not always) set in Regency, Victorian, or Edwardian London (the 19th and very early 20th century). It may be identical to the real world of that time period, or it may be an alternate history. Gaslight Fantasy is recognizably different from Steampunk Fantasy. While Steampunk focuses on alternate developments in technology and may not have any magic at all, Gaslamp plots focus on supernatural elements and frequently draw on elements of Gothic romance and/or Gothic horror fiction.

Some novels combine both dystopian and post-apocalyptic elements to point out that society can make different choices as it rebuilds. The TV series Revolution (9/2012—5/2014) is an example. The action in that story takes place 15 years after a worldwide power blackout (the post-apocalyptic element). Even since the power went out, various people have been forming, defending, and/or rebelling against governments, each of which promotes itself as the best, but each of which oppresses its citizens, forcing them to conform to repressive laws and totalitarian military authority (the dystopian element).
Soul Mate: the one and only true love of one's life. In paranormal fiction, supernaturals frequently mate for life with their soul mates. If one dies, so does the other. In many cases, the couple must go through a specified process in order to officially become bonded mates. In Lora Leigh's BREEDS series, the soul-mate status is so important that it drastically affects the love-making process. Here are some examples of other names that authors use instead of "soul mate": bond mate, life mate, breed mate, true soul pairing, beloved, jun tan, and cónyuges. In Leigh Evans' MYSTWALKER series, the heroine calls her hero her "one true thing."

UF (Urban Fantasy): An urban fantasy (UF) novel is generally set in a dark and gritty cityscape in an alternate, but contemporary, world that has a mythology carefully constructed by the author (aka world-building). The UF protagonist is generally an insecure loner with some type of developed or undeveloped supernatural power (e.g., necromancer, wizard, witch, empath, psychic, shapeshifter). He or she lives in an urban environment, usually in the contemporary world but sometimes in a fictional, but realistic, world, and faces life with a cynical attitude. The protagonist is often adopted, with birth parent(s) who deserted or died during his or her infancy. The mysterious parentage is an important ingredient in most UF fiction. One or both of the missing parents is usually a supernatural being and provides the genetic background for the protagonist's own magical powers. Female protagonists frequently have red hair and green eyes. Frequently, the protagonist tells the story in a first person narrative, and the story arc extends over several books—or over the entire series. Modern UF stories/series can contain elements of mystery, horror, and romance, but to varying degrees.
