Fantasy.

Stardust by Neil Gaiman and Charles Vess': "One star fell" (Gaiman and Vess' 59). The movie Stardust is a wonderful tale of romance, war and fantasy. The novel is much different than the movie and a million times better.
In our case, a star is just a captured meteorite that, for some obscure reason, shines at night. In this novel, however, a star is not a meteorite but a person; a beautiful woman that shines and radiates beauty with from every inch of her body. But, it is also told that if one posesses the heart of a star, one is granted immortality. Strong princes and terrifying witches seek the star, hoping to capture her heart and gain immortality. (Capture her heart is meant quite literally. To cut out her heart and eat it.)
