"Twilight" hit the bookstores and the pop-culture world like a hurricane. Millions of young people (OK, some weren't so young) fell in love with Edward Cullen and Bella Swan, rooting for their star-crossed relationship to work out. Three sequels, equally successful, followed.
Then, before we could catch our breath, a second hurricane made landfall: "Fifty Shades of Grey." Nothing could dissipate the power of this distinctly-not-for-kids book, not even the revelation that it was based on a "Twilight" fanfiction called "Master of the Universe," and that its author had posted it under the try-to-keep-a-straight-face name "Snowdragon's Icequeen." Not the typical path to the bestseller lists, that's for certain.
Despite the difference in the two books -- Stephenie Meyer's tale of a chaste relationship between a high-school girl and her courtly vampire lover, and E.L. James's explicit NFSW prose -- many people devoured both books (and the sequels that followed).
So -- can you keep straight which debut novel is which? Who drove a silver Volvo, and who flew the helicopter Charlie Tango? Which heroine got dangerously drunk in public, and which was nearly hit by a van? With one book being closely modeled on the other, there are more similarities than you might think. Good luck!
