Paranormal romance partially coincident with Time travel romance
Definition and subgenres
Paranormal romance blends the real with the fantastic or science fictional. The fantastic elements may be woven into an alternate version of our own world in an urban fantasy involving vampires, demons, and/or werewolves, or they may be more "normal" manifestations of the paranormal—humans with psychic abilities, witches, or ghosts. Time travel, futuristic, and extraterrestrial romances also fall beneath the paranormal umbrella.These novels often blend elements of other subgenres, including suspense and mystery, with their fantastic themes. A few paranormals are set solely in the past and are structured much like any historical romance novel. Others are set in the future, sometimes on different worlds. Still others have a time-travel element with either the hero or the heroine traveling into the past or the future. Between 2002 and 2004, the number of paranormal romances published in the United States doubled to 170 per year. A popular title in the genre can sell over 500,000 copies.As in the fantasy subgenre known as urban fantasy, many paranormal romances rely on the blend of contemporary life with the existence of supernatural or magically empowered beings, human or otherwise; sometimes the larger culture is aware of the magical in its midst, sometimes it is not. Some paranormal romances focus less on the specifics of their alternative worlds than do traditional science fiction or fantasy novels, keeping the attention strongly on the underlying romance.  Others develop the alternate reality meticulously, combining well-planned magical systems and inhuman cultures with contemporary reality.
The first futuristic romance to be marketed by a mainstream romance publisher, Jayne Ann Krentz's Sweet Starfire, was published in 1986 and was a "classic road trip romance" that just happened to be set in a separate galaxy. This genre has become much more popular since 2000. Krentz attributes the popularity of this subgenre to the fact that the novels "are, at heart, classic historical romances that just happen to be set on other worlds".Time-travel romances are a version of the classic "fish out of water" story. In most, the heroine is from the present day and travels into the past to meet the hero (for example, the manga and anime series Inuyasha). In a smaller subset of these novels, the hero, who lives in the past, travels forward into his future to meet the heroine. A successful time-travel romance must have the characters react logically to their experience, and should investigate some of the differences, both physical and mental, between the world the character normally inhabits and the one in which they have landed. Some writers choose to end their novels with the protagonists trapped in different time periods and unable to be together—to the displeasure of many readers of the genre.
